■ Introduction:
Nitride bonded silicon carbide burning plate batts are designed for exceptional corrosion and thermal shock resistance. Nitride Bonded Silicon Carbide burning plate batts have desirable refractory and chemical properties. The Nitride bonded refractory materials share common features including an outstanding hot mechanical strength and a low pores size that confers a low permeability to gas as well as a superior infiltration resistance to molten metal and slag and a low wettability.Nitride bonded silicon carbide burning plate batts as kiln furniture are used in high temperature resistant industrial.
