High Temperature Resistant Coating Use HBN Nanopowder 
	Specification of hexagonal boron nitride powders: 
	Particle size: 100-200nm, 0.8um, 1-2um, 5-6um 
	Purity: 99%, 99.8% 
	Color: white 
	Crystal form: hexagonal 
	Other nitrides Hongwu supply: Si3N4, AlN, TiN 
	
 
	Good performance of HBN powder at high temperature: 
	Boron nitride has a significant chemical inertness at high temperatures, allowing boron nitride(BN) coatings to protect materials such as aluminum, magnesium, zinc alloys from high temperature oxidation. 
When the boron nitride coating is on a refractory material or a ceramic vessel, it can effectively protect its oxidation resistance even at a temperature of up to 1273K.
