Silicon boron nitride ceramic uses silicon carbide and zirconia binder system.
DMCERA® Silicon Boron Nitride
Silicon boron nitride ceramic BN-SZ uses silicon carbide and zirconia binder system. We improve thermal shock resistance and erosion resistibility, then promise BN-SZ can work well in high temperature and high wear.BN-SZ ceramic is the best choice for break ring of horizontal continuous casters and nozzles of amorphous thin-strip. It has a wide variety of molten-metal-contact applications with properties.
Advantages:
● Good chemical stability.
● Good thermal shock resistance.
● Mechanical strength and thermal durability.
Applications:
● Break rings of continuous casting
● Side dams for thin strip casting
● Component for MOCVD equipment.
● A variety of molten metal contact applications
● Nozzles for metal atomizing and powder metal atomization.
