Pure Si3N4 (Silicon Nitride /Sialon)Ceramic is a super good advanced material in the world, it’s made from high quality Si3N4 powder with leading tech & equipments. Tangshan Hanwei offered Si3N4 (Silicon Nitride )Ceramic has following features:

1)      High hardness, wear resistance;

2)      Very small thermal expansion;

3)      Electrical insulating material;

4)      Stable chemical property, corrosion resistance;

5)      Higher machnical strength....

By its perfect Pysical, chemical & mechanical performance, widely applied on Metallurgy,chemical,new energy, aeronautical and space field etc. Here we introduce metallurgy application, especially for molten metal Aluminum,Cu, Zn etc, as heater protection tube,thermocouple protection tubes,stalk riser tube for low pressure die casting,stopper pipe,degassing pipe & rotor. But due to current tech limited, now only few manufacturers can make it, typically Japan KYOCERA Corporation, fortunately China also can do it, Tangshan HanWei actived in SiC ceramics over 6 years, gathering all producers’s advantage, only for offering most right solutions for every customer!

Actually Pure Si3N4 (Silicon Nitride )Ceramics price is very expensive, some industries is no need it cause of cost saving, thus another ceramic is coming, that’s Si3N4-SiC ceramics, short name N-SiC Ceamic!  Tangshan HanWei supplied NSIC ceramic products has very similar performance with  pure Silicon Nitride, but price is much more competitve. TSHW sincerely welcome anyone to inquiry kinds of SiC ceramics at any time!
