Silicon Carbide Ceramic Wafers

As manufacturer and supplier of industrial ceramics , Chemshun Ceramics supply silicon carbide ceramic plate as bulletproof body vest protective materials . more ballistic armor ceramic shapes includes Square, rectangle, triangles , hexagonal etc. Customized shapes acceptable.

We strictly control the raw materials and produce the prilling powders for ourselves. The density of our sic tiles can be above 3.14g/cm3, and hardness above 2650n/mm2, which reached the international advanced level. Our quality armor sic tiles have exported too many countries, we all get very good feedbacks. Our newly developed 250¡á300mm monolithic sic armor plate also gives our clients morechoices. We produce silicon carbide ceramics of various shape and size.So the size and dimension are customerizable.

Silicon carbide balls are less frequently used than other ceramic materials. Due to its raw material costs and difficulty to machine. Silicon carbide offers the best heat and corrosion resistance of all the ceramic materials. Silicon Carbide is best used under low loads, low to moderate speeds and in highly corrosive environments. Used In : Ceramic Bearing & Ceramic Tube

Si3N4 Ceramic Substrate Manufacturer,Silicon Nitride Ceramic For IGBT,Power Module Substrates,LED Substrate Product Description Silicon Nitrides (Si3N4) Feature An Excellent Combination Of Material Properties. They Are Nearly As Light As Silicon Carbide (SiC), But Their Microstructure Gives Them Excellent Thermal Shock Resistance And Their High Fracture Toughness Makes Them Resistant To Impacts And Shocks. Properties Of Silicon Nitride (Si3N4) Very Low Density (3.21 G/Cm3) Very High Fracture Toughness (7 MPam1/2) Good Flexural Strength (850 MPa) Very Good Thermal Shock Resistance: High Thermal Stress Parameters (569 K) Maximum Operating Temperature In An Oxidizing Atmosphere: 1,300°C Maximum Operating Temperature In A Neutral Atmosphere: 1,600°C Feature High Strength (High Reliability) Similar To The Thermal Expansion Coefficient Of Semiconductors Such As Si, SiC, And GaN High Dielectric Strength High Bending Strength Main Use Of Precision Ceramics For Electronics (Si3N4=Silicon Nitride) Power Module Substrates LED Substrates Submount For Optical Pick-Up Heat Dissipation Substrates The porous silicon nitride ceramic material combines the excellent properties of both the silicon nitride ceramic and the porous ceramic and is a ceramic material having a communicating or closed pore in the body. Porous silicon nitride ceramics have been widely used in aerospace and environmental chemicals due to their special structure and properties, such as low density, high porosity, moderate dielectric properties, high specific surface area, high hardness, and high fracture toughness. Important fields such as biomedicine, national defense, and military.

silicon nitride ceramics Silicon nitride ceramic is an inorganic material ceramic that does not shrink during sintering. The strength of silicon nitride is very high, especially hot-pressed silicon nitride, which is one of the hardest substances in the world. It has high strength, low density, high temperature resistance and other properties. High temperature resistance, the strength can be maintained to a high temperature of 1200 without decreasing, and will not melt into a molten body after being heated, and will not decompose until 1900 It has amazing chemical corrosion resistance, and can withstand almost all inorganic acids and less than 30% caustic soda solution, as well as many organic acids; It is also a high-performance electrical insulating material. Si3N4 can be used to manufacture ball bearings by virtue of its light weight and high rigidity. It has higher accuracy than metal bearings, generates less heat, and can operate in higher temperatures and corrosive media. The steam nozzle made of S ceramic has wear resistance, heat resistance and other characteristics, and it will not be obviously damaged after being used in 650 boiler for several months.
