green silicon carbide chemical stability

 high thermal conductivity, thermal expansion coefficient, good wear resistance, except for the abrasive used, there are many other uses, synthetic diamond such as: a special process the silicon carbide powder coating on the cylinder block of the turbine impeller or wall, can improve the wear resistance and extend the life of 1 to 2 times; for advanced refractory materials, heat shock, small size, light in weight high strength, good energy saving effect. A low-grade silicon carbide (containing about 85% SiC) CBN abrasive grit is an excellent deoxidizer, with its speed steel to accelerate and facilitate control of the chemical composition, to improve the quality of steel. In addition, silicon carbide heating element is also used extensively for the production of silicon carbide. Silicon carbide's hardness great, Mohs hardness of 9.5, second only to the world's most hard-diamond (10), has excellent thermal conductivity, is a semiconductor, resistant to oxidation at high temperatures.

the hardness between corundum and diamond

Formula SiC, the hardness between corundum and diamond, corundum higher mechanical strength can be used as an abrasive and certain other industrial materials. The successful development steel fiber for concrete reinforcement  of industrial use of silicon carbide in 1891, is the oldest artificial abrasive. Although meteorites and the Earth's crust in a small amount of silicon carbide exists, but has not yet been found for the exploitation of mineral resources.black silicon carbide In addition, silicon carbide heating elements are also used extensively for  fused zirconia mullite  the production of silicon carbide.
The great hardness of silicon carbide having excellent thermal conductivity, is a semiconductor, is resistant to oxidation at high temperatures.
Since the stacking sequence of α-SiC crystal structure different from carbon and silicon atoms to constitute a number of different variants have been found more than 70 species. β-SiC into α-SiC at the time of over 2100 ℃.

Green silicon carbide is suitable

Green silicon carbide is suitable for grinding wheel to the outer code processing GC carbide, glass, ceramic and metallic materials, is also used for a semiconductor material, Glass beads  high temperature silicon carbide heating element, far-infrared source substrates and the like.
According to the shape can be divided into flat-shaped grinding wheel, bevel grinding, cylindrical grinding wheels, cup wheels, disc wheels, etc.; binding agents can be classified according to the ceramic wheel, resin wheel, rubber wheel, metal grinding wheel.
Wheel after working synthetic diamond for a period of time, should be trimmed to restore grinding performance and correct geometry.
The main characteristic parameters of the abrasive wheel, the viscosity, hardness, binders, shape, size and the like. Since the wheel is usually working at high speed.

black silicon carbide chemical stability

Black silicon carbide and silicon carbide green silicon carbide two common basic varieties, Silicon carbide due to chemical stability, high thermal conductivity, thermal expansion coefficient, good wear resistance, except for the abrasive used, there are many other uses, such as: a special process the silicon carbide powder coating on the cylinder block turbine impeller or wall, can improve the wear resistance and extend the life of 1 to 2 times;  black silicon carbide for advanced refractory material, heat shock, small size, light weight high strength, good energy saving effect. A low-grade silicon carbide (containing about 85% SiC) is an excellent oxygen scavenger, which can be used to accelerate the speed of the steel brown fused aluminum oxide  and to facilitate control of the chemical composition, to improve the quality of steel. In addition, silicon carbide heating elements are also used extensively for the production of silicon carbide.
The great hardness of silicon carbide having excellent thermal conductivity, is a semiconductor, is resistant to oxidation at high temperatures.

green silicon carbide Grit Features

Grit Features: moderate hardness, toughness, impact resistance, can be repeated several times using continuous, long life, good rebound, strong adhesion, clean up fast low consumption of sand, not broken, green silicon carbide clean up the workpiece brightness, good technical results, this product is processed through the metal surface cleanliness of up to international standards. Surface roughness of 25--150um, thus increasing the contact surface of the metal surface to improve the surface adhesion smear of refined metal surface hardening metal structure, with a very significant economic benefits,waterjet abrasives  is the most advanced home and abroad, most ideal blast cleaning, descaling and enhanced quality materials. 

Grit raw material is high-carbon steel fused zirconia mulliteor alloy steel scrap material.

A direct use of scrap material preparation process grit.  sandblasting material  ‍Comprising the steps of:

(1) made ??of high carbon steel or / and alloy steel scrap material, into the quenching apparatus for heating quenching;

(2) heating after quenching scrap material into the crusher, get grit semi;

(3) The grit semi sorting that prepared the finished grit. Grit production method of the present invention to reduce the traditional production process must grit cast steel shot into the scrap smelting and manufacturing processes pill, saving the cost of production. ‍

white aluminum oxide Fused brick

Fused Fused zirconia corundum brick brick brick , also known as the abbreviation is AZS, is based on three chemical composition Al2O3-Zr02-Sio2 ternary phase diagram , according to their order of how much content , Al2O3 take A, Zr02 take Z, Sio2 take S, using the abbreviation for national standards , such as 33 cast AZS bricks, abbreviated as AZS-33 #, 36 cast AZS bricks, abbreviated as AZS-36 #, white aluminum oxide‍ 41 cast AZS bricks, abbreviated as AZS- 41 # .

Fused brick manufacturing process will be a selection of zircon sand and industrial alumina powder with 1:1 , plus a small amount of NaZO ( in the form of sodium carbonate is added ), B20: ( in the form of boric acid or borax added ) flux , mixed uniform , after the 1900 ~ 2000 ℃ melt cast molding , can be prepared containing zr0233% of the cast slabs . On this basis , the use of part desilication zircon sand as raw material , can be obtained with ZrO2 36% ~ 41% of the cast slabs . gaogangyuzhuan corundum brick (z irconia-eorundumrefraetory brick) using industrial alumina powder and a selection of zircon sand as raw material , ZrO2 content is made ??of 33% to 45 % of the refractory products . White fused aluminum oxide‍ Fused zirconia corundum brick is mainly used in the glass industry furnaces , electric glass furnace, the steel industry 's slide, sodium silicate industry kilns and other high temperature erosion -resistant refractory kiln

black silicon carbide Silicon carbide

Silicon carbide products can be divided into many categories, depending on the use of the environment, divided into different categories. To the more general use black silicon carbide‍ of the machinery. For example, to the use of mechanical seals, silicon carbide seal ring can be called, can be divided into static ring, ring, flat ring. Also according to special requirements of customers, produce a variety of shapes silicon carbide products, such as silicon carbide shaped pieces, carbide plates, carbide ring.The article of one of silicon carbide SiC having high sandblasting material‍ hardness, high corrosion resistance and high temperature strength characteristics, so that the silicon carbide ceramic which has been widely used.Uniformity is white aluminum oxide‍ good - round rate greater than or equal to 80%, uniform size, so after spraying sand around the device to maintain a uniform brightness factor, not easy to leave a watermark. Okay abrasive.
