Ceramic Nozzle For Atomization Of Steel
Boron Nitride ceramic nozzles are widely used in the processing of atomization of steel. As its high strength, high melting point, high toughness, and outstanding thermal shock resistance, steel powder manufacturers use Boron Nitride material to make the atomizing nozzle. Also, BN material has no reaction or wetting with molten metals. INNOVACERA developed a wide range of BN grades for the nozzles to meet the needs of different end users.
