Cutting Si3N4/SiC Composite Ceramics Refractory Brick for Fine Ceramics Industry

 Si3N4/SiC composite ceramics refractory brick for fine ceramics industry

Si3N4/SiC composite ceramics refractory brick has been a research hotspot in the field of fine ceramics for the past two to three decades, and the corresponding theories have been quite mature, and there have been many research results. Compared with Si3N4 ceramics refractory brick, Si3N4/SiC composite ceramics refractory brick have more excellent high-temperature performance. This is because Si3N4 will exhibit grain boundary slip at high temperatures, which deteriorates its performance. Therefore, most of the current methods are to introduce SiC particles or whiskers into Si3N4-based ceramics. Through a special sintering method, the SiC particles/whisker toughening phase can quickly enter the Si3N4 grain boundary, and the anchoring effect of the Creep resistance at high temperature, thereby improving the overall high temperature performance of the sample. On this basis, Si3N4/SiC composite refractory brick have been widely used. Due to their high-temperature strength, low thermal diffusion coefficient, and good thermal shock resistance, Si3N4/SiC composite refractory brick have become the most popular in high-temperature or ultra-high temperature fields. The promising high-temperature composite structure ceramics.

SiC materials are exposed to exceptional corrosive conditions, thermal conditions and abrasive conditions when applied in combustion chambers of waste incineration plants or high temperature furnaces. SiC bricks with silicon-aluminium-oxynitride bonding and with a grain matrix from cubic SiC are well suited for the latter stress applications. A purpose related material composition, the application of different shape related shaping processes, and firing in the best possible oxygen free atmoshpere ensures SiC products are produced with excellent performance characteristics.

Silicon Nitride Bonded Sic Brick / SiC brick is made of high quality synthetically made silicon carbide grains (SiC) and selected bonding components, including nitride, Si3N4.
Silicon Carbide bricks has great features such as high thermal conductivity, high thermal shock resistance, low thermal expansion coefficient, high corrosion resistance, high bending strength, and excellent resistance to liquid aluminum erosion capability.
SiC brick is particularly ideal for application in high temperature furnaces and in waste incineration plants.
The Si3N4 SiC blocks are widely used as lining bricks of large aluminum electrolytic cell. Using nitride bonded silicon carbide products enlarges the tank capacity, improves the thermal conductivity, enables rapid cooling, and increases the tank production capacity at the same time. Alumina and cryolite of eutectic content can form on bricks' surface, which can protect the tank lining work layer, and prolong the tank's service life. Therefore, silicon nitride bonded silicon carbide bricks are widely used in the aluminum industry.

Silicon Carbide brick is a new kind of bullet-proof ceramic material, with low density, high strength, high hardness, high temperature resistance, oxidation resistance, corrosion resistance and other excellent performances. Now it's the preferred general material for bulletproof ceramic pieces, mechanical seals, sand jets as well as magnetic pumps, shielding pump components, etc.
We produce sintered silicon carbide ceramics taking high purity sub-micron silicon carbide powder as raw material, according to the advanced formula imported from Japan, through the spray granulation, pressure molding and high temperature vacuum sintering. As the structure inside is compact, small grains, bullet-proof performance of this product is superior. The breast armor plates made of silicon carbide from our company have reached the standard NIJ0101.06III,IVand passed the grade IIIV bullet-tests held by National Bulletproof Equipment Testing Center for many times. Furthermore this product has successfully passed the target test certificated by the PLA. Nowadays the PLA troops are equipped with this ceramics composite armor.

Silicon Carbide brick is a new material produced at a specific high temperature and pressure environment , the main ingredient is silicon nitride. Si3N4 content above 80% -97.5%. Phase composition and purity can be produced separately according to user requirements. main feature:
1, It has good corrosion resistance, thermal shock and abrasion resistance. It can be used at a temperature of 1900 degrees Celsius.
2,It has an excellent split endurance, very stable chemical composition and thermal conductivity.
3, The product contains nitride, with characteristics of small swelling, heat conductivity and high strength and almost no shrinkage about its heat.
4, It can produce a high temperature oxide film on the surface, and affect the future protection of the interior material not subjected to chemical reaction.
