RAW MIX FOR PREPARING PHOSPHATE BINDER Russian patent published in 1999 - IPC

FIELD: production of refractory materials, more particularly preparation of slag-, steel- and iron-resistant compositions used for repair of steel teeming ladles and also for manufacture and repair of refractory linings and furnace assemblies including heat-insulating concretes. SUBSTANCE: raw mix comprises (wt %): finely dispersed petrochemical industrial waste, 15.0-23.0; spent phosphating solution in terms of pure phosphorous acid, 20-30; titanium-containing compound in terms of pure titanium dioxide, 0.5-10; boric acid, 0.5-0.7; mortar, 3.0-25.0; and refractory clay, the balance. EFFECT: smaller amounts of raw mix for preparation of refractory chemically resistant compound due to using readily available and cheap components.
