Material Characteristics
Pressureless sintered silicon carbide (S-SiC) is made of high-purity silicon carbide (SiC) micropowder as raw material. After forming by dry pressing, slip casting or isostatic pressing, densification sintering is conducted in a high-temperature furnace under atmospheric pressure and inert gas protection at a sintering temperature of about 2100-2200℃. This process can produce high-performance ceramics with a theoretical density of over 98%, uniform microstructure and no free silicon residue. The product features extremely high hardness, excellent corrosion resistance, oxidation resistance and wear resistance, and is widely used in industrial kilns, electronic materials, semiconductors and other industries.

Product Applications:
S-SiC temperature sensor protection tubes are widely used as protective sleeves for temperature measurement in non-ferrous metal smelting and casting, anti-corrosion isolation tubes for sensing components in chemical reactors and coal gasification furnaces, furnace temperature protection tubes for ceramic and glass kilns, atmosphere temperature measuring sleeves for heat treatment furnaces and powder metallurgy sintering furnaces, as well as flue temperature protection sheaths for waste incineration and waste heat power generation systems. It acts as a key protective component to guarantee temperature measurement accuracy and service life under high temperature, strong corrosion and gas scouring working conditions.
