SiSiC Tubes is a new advanced silicon carbide material, which developed on the basis of primary high performance RSIC and NSIC and an economic and value added product with features of high degree of reliability, longer working life and energy efficiency.
NSiC Tubes is made of a select grade and high-purity silicon carbide powder and Si powder, formed by slip casting, reacted and sintered by vacuum induction sintering furnace. This kiln furniture has high temperature strength and low mass.
RSiC Tubes is made of a select grade and high-purity silicon carbide powder, consolidated by vacuum induction sintering furnace at temperature 2450℃.The product is without any additive composition.
