Shaped Refractory Products And Method Of Making Same

Abstract

The method of making a foamed, low density shaped refractory product consisting of TiB2 and Al2 O3 which comprises the steps of foaming an exothermic reaction mixture consisting of TiO2, B2 O3 and Al, loading the reaction mixture into a self sustaining shape, locally igniting the shaped reaction mixture in air at ambient conditions and recovering the foamed, low density, shaped refractory product.
