high thermal conductivity Alumina Ceramic Substrate chip
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
99.70% corundum 1800 ° C 1650 ° C -1700 ° C corundum in the oxidation and reducing atmosphere, has good high temperature insulation and mechanical strength. The thermal conductivity is large and the thermal expansion rate is small. It does not react with air, water vapor, hydrogen, carbon monoxide or the like above 1700 °C. The short-term maximum operating temperature is 1800 °C. 99.35% corundum 1750 ° C 1600 ° C - 1650 ° C corundum in the oxidation and reduction atmosphere. 85.00% high aluminum 1350 ° C 1290 ° C high aluminum crucible in the oxidation and reducing atmosphere, has good high temperature insulation and mechanical strength. The thermal conductivity is large and the thermal expansion rate is small. Does not react with air, water vapor, hydrogen, carbon monoxide, etc. It can be used for a long time when the temperature of the temperature field does not change much. The short-term maximum operating temperature is 1400 °C. The raw materials for production can be summarized into three major types. One is crystalline natural graphite, the other is plastic refractory clay, and the third is calcined hard kaolin skeleton clinker. Since 2008, high-temperature resistant synthetic materials such as silicon carbide, alumina silicon carbide and ferrosilicon have been used as skeleton skeleton clinker. This clinker has a significant effect on improving the quality of niobium products, enhancing tantalum density and mechanical strength. Quartz crucible can be used below 1650 degrees, both transparent and opaque. The translucent quartz crucible made by the arc method is a large-diameter single crystal silicon, which is an indispensable basic material for the development of large-scale integrated circuits. Today, the world's semiconductor industry developed countries have used this to replace small transparent quartz crucibles. It has the advantages of high purity, high temperature resistance, large size, high precision, good heat preservation, energy saving and stable quality.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
