Product Description
Products descirbeSiC ceramics not only have excellent mechanical properties at room temperature , such as high bending strength , good oxidation resistance , good corrosion resistance , high wear resistance and low friction coefficient , but also the high temperature mechanical properties ( strength , creep resistance , etc . ) are the best materials in the known ceramic materials . The high temperature strength can be maintained to 1600 ºC , which is the best material of high temperature strength in ceramic materials . The oxidation resistance is also the best material in all non - oxide ceramics .Characteristics:1. Excellent thermal stability and distortion resistance at high temperature.
2. Superior corrosion resistance.
3. Low apparent porosity and thermal expansion.
4. Outstanding thermal shock resistance.
5. Excellent thermal conductivity.
6.Excellent oxidating resistance.| Index | RSIC | NSIC | SISIC | SI3N4-SIC |

Application
1.Aluminum nitride powder with high purity, small size, high activity, is the main raw material for the manufacture of high thermal conductivity aluminum nitride ceramic substrate.
2.AlN ceramic substrate, high thermal conductivity, low expansion coefficient, high strength, high temperature resistance, chemical corrosion resistance, high resistivity, dielectric loss is small, think of the large scale integrated circuit substrate and packaging materials.
3.More than the traditional aluminum nitride alumina, high hardness, abrasion resistant ceramic materials is new, but because of its high cost, only for the serious wear of the parts.
4.High melt erosion and thermal shock resistance of AIN ceramics by heat, can be made of GaAs crystal crucible, Al evaporation dish, magnetic fluid generating device and the high temperature corrosion of turbine components, using the optical properties for infrared window. Aluminum nitride thin film can be made of high frequency piezoelectric element, ultra large scale integrated circuit substrate.
5.Aluminum nitride, heat resistance, erosion resistance of molten metal, but the acid stability in alkaline solution Easy to be eroded.AIN new surface is exposed to moist air will react very thin oxide film. Using this characteristic, can be used as aluminum, copper, silver, lead and other chemical properties of metal crucible for metal melting and casting mould of.AIN ceramics is better, can replace toxic beryllium oxide ceramics are widely used in electric industry.
