China manufacturing for silicon nitride heating tubes
Silicon nitride, which has the chemical formula Si3N4 and is a significant structural ceramic material, is the major component of silicon nitride heating tubes. An atomic crystal, silicon nitride is a superhard material that is naturally lubricious, resistant to abrasion, and resistant to oxidation at high temperatures. In addition, it can withstand thermal shock, withstand air temperatures above 1000 °C, and withstand fast cooling followed by quick heating without breaking.
The strength of the silicon nitride heater tubes is capable of being maintained at temperatures as high as 1200 ° C without deteriorating. It does not melt into a melt when heated, and it does not begin to decompose until a temperature of 1900 °C. It also has amazing chemical resistance, being able to withstand almost all inorganic acids, as well as many organic acids, and not being wetted or corroded by many different kinds of molten metals or alloys, such as aluminum, lead, tin, silver, brass, nickel, etc. Due to its distinct performance advantages, silicon nitride protection tube, a high-performance electrical insulation material, has been well received by the market.
