Abstract:
A high alumina refractory and its preparation are disclosed. In addition to the mix of alumina particles providing an Al. sub. 2 O. sub. 3 content of at least 50%, by weight, there is included metallic carbide particles, having a critically-selected particle size distribution, in an amount between about 3 and about 25%, by weight, based on the total dry weight at the mixture. Other forms of carbon, like tar, pitch and graphite are omitted. The product is free from black core and has improved resistance to molten slags and metals.
