The series products of Si3N4B is reaction-sintered Si3N4 high-temperature structural ceramic materials with excellent properties such as high strength, high temperature resistance, corrosion resistance, thermal shock resistance, oxidation resistance, wear resistance and self-lubrication. The specific properties of Si3N4A are shown in Table 2.2.
The series products of Si3N4B have a wide range of applications in aerospace, automotive, machinery, petrochemical, metallurgy, building materials, ceramics, power, electronics and other fields. It include (1) kiln furniture used in the ceramic industry, (2) thermocouple protection tube, heating element protection tube, (3) hot-dip galvanized inner heating radiant tube, zinc pot, zinc dipping sleeve, compression roller and etc., (4) rising tube, conduit, spiral agitator, stir bar, aluminum flow tanks and etc. used in the aluminum alloy low-pressure casting and die-casting industries, (5) pipes, valves, desulfurization nozzles in the petrochemical industry, (6) high-temperature furnace tubes of various shapes, (7) filters for the alloy melt.
The Si3N4B products are especially suitable for non-ferrous metals industry, such as aluminum, zinc, copper alloy melting and casting industry. It has not only good thermal shock resistance, oxidation resistance, but also the properties of acid and alkali corrosion resistance and high temperature resistant metal liquid scour.
