Effects of Carbonates, Carbon, Chromium Oxide and SiC Compositions On Steel Slag Sintering

Amorphous slag from the electric arc furnace of Mobarakeh Steel Company, and soda ash flute glass waste (window, mixed with equal weight ratio and sintered with foaming agents and used to prepare glass-ceramic foam. Five types of foaming agents including silicon carbide, calcium carbonate, chromium oxide, graphite and barium carbonate were added to the base composition in five amounts and sintered at 1200 ° C.The crystalline phase crystallized in the composite was at a low weight percentage of foaming agent wollastonite and with increasing weight percentage by 5% Pesudo wollastonite-.The highest volume increase is related to the sample with 5% by weight of barium carbonate and the highest porosity is related to silicon carbide with 1% by weight.The highest compressive strength among the three approved compounds reaches 4.8 MPa in terms of microstructural content of the sample with a weight percentage of calcium carbonate.Also, the distribution of porosity in all foam foams used is non-uniform and only chromium oxide has a better distribution than others.
