As a high-grade refractory product, silicon carbide tank (saggar) is currently an ideal refractory material for firing lithium battery anode materials and powder metallurgy industry (sponge iron large tunnel kiln). The silicon carbide tanks produced by the company use high-grade silicon carbide raw materials with a content of 98%, and a special process has been added to the selection of raw materials to ensure the high purity of raw materials.
The physical and chemical indicators of the silicon carbide tank are as follows:

Items Specifications
SiC % ≥86
SiO2  % ≤10
Al2O3  % ≤1.0
BD g/cm3 ≥2.6
AP % ≤15
CCS MPa ≥100
CTE 10-6/℃ 5.2
RUL ℃ ≥1600
TSR, cycle (1000℃, air-cooling) ≥200
