FOAMED SHAPED REFRACTORY PRODUCTS OF TIB2 AND AL203 AND METHOD OF MAKING SAME

摘要

we make a product molded foam, low density, and tib2 and refractory consisting of al2o3 to form a reaction mixture consisting of tio2 and b2o3 exothermic, al, loading the reaction mixture (12) in a crucible (10) having a separate core filled with powder al2o3 (14).in the setting of locally in ambient air conditions, the reaction mixture is shaped by recovering the produced molded foam, low density, and refractory (p), which is the material of the core (c), and eliminating the latter.
