Product Description:

PN-SCN series of silicon nitride bonded silicon carbide blocks are fired at high temperature in nitriding furnaces, manufactured with high-purity SiC as the raw material and silicon powder as additives based on situ theory.

Its micro structures indicate SiC grains are evenly surrounded by phases which are composed of granular SiC and fibers that interlace three-dimensional network, to embrace smaller SiC grains and form strong mechanical bonding with big SiC grains.

These products are used in the electrolyte baths to decrease the working lining thickness and increase the bath’s volume. They feature high thermal conductivity, oxidization resistance and cryolite resistance, and they are especially suitable for high-power baths.

PN-SCN blocks have been supplied to many big aluminum electrolyte baths in China and overseas like Jiaozuo Wanfang Aluminum, Guiyang Aluminum, Zhongfu Aluminum, Baotou Aluminum, BSL and RUSAL, etc.

Packing: Seaworthy packing in wooden pallet.

Transportation & Storage: Keep dry and handle with care.

Shelf Life: 2 years.
