Description
Silicon Nitride Si3n4 Ceramic Hardness Plate,the series of products are widely used for measuring temperature in the fields of ceramic, metallurgy, chemical industry.Silicon Nitride Si3N4 Ceramic is one kind of technical ceramic materials which has very good performance in high temperature, its mechanical strength can be kept up to 1200ºC. Its hardness and wear resistance performance ranks high among all technical ceramic materials. It has high electrical resistivity, high dielectric constant and low dielectric loss, is a choice for electrical insulation. Furthermore, it has good chemical stability and resistance to oxidation. As a result, silicon nitride ceramic has the best comprehensive performance and most wide application in high temperature field.
