Thermal conductivity of SiC
Silicon carbide is a kind of single-phase, non-pressure sintered silicon carbide ceramics with high purity, fine crystal and very low porosity. It can be used as a suitable substitute for graphite, stainless steel, tantalum metal, Hastelgold, fluorine plastics and other traditional materials. In the chemical industry, medicine, metallurgy and other industries of high temperature, high pressure, strong corrosion, high wear in the extreme environment. High-performance silicon carbide heat exchanger has the characteristics of high strength, high temperature resistance, high thermal conductivity and comprehensive acid and alkali corrosion resistance of silicon carbide ceramics. It is especially suitable for high temperature, high pressure, strong acid and alkali corrosion, high-speed airflow erosion, particle wear and other harsh working conditions. Its excellent heat exchange efficiency can meet the urgent needs of energy saving, emission reduction and environmental protection.
The pressureless sintered silicon carbide ceramic products produced by our company are made of ultra-fine
silicon carbide powder sintered at high temperature. The silicon carbide content is above 98%, the product
density is ≥3.10g/cm³, without free silicon. The performance indexes of the products reach the international
advanced level (to the technical standards of Morgan in England and Saint-Gobain in France).What's more, the
products have a great deal of technical advantages, such as high mechanical strength, high hardness, wear
resistance, high temperature resistance, strong acid and alkali corrosion resistance, oxidation resistance,
thermal shock resistance, good thermal conductivity, extreme cold and heat resistance and high temperature
creep resistance. As a result, the products are widely used in many higntch fields, such as military industry,
aerospace, nuclear power, metal smelting, high-temperature furnace, lithium-ion battery production, powder
metallurgy, ceramic chemical machinery, ultra-fine grinding, papermaking, medicine and so on.
