melt and with the experimental data, the four coefficients for foaming process can be determined in the variations of crucible diameter, slag height and foaming agent radius. In this way the foam behavior of foaming process under different conditions can be compared quantitatively. [ Keyword: foaming slag; foam originated from reaction; average foaming life; foaming......
Influence of aluminium nitride as a foaming agent on the preparation of foam glass-ceramics from high-titanium blast furnace slagHuan Shi1,Ke-qin Feng1,Hai-bo Wang1,2,Chang-hong Chen1,Hong-ling...-titanium blast furnace slag(TS), foam glass-ceramics were successfully prepared by powder sintering at 1000°C.
