Abstract
The problems associated with the use of chromic acid (CrO.sub.3) binders are substantially overcome by a basic refractory monolith incorporating molybdenum trioxide (molybdic oxide, moO.sub.3) as the binding agent. In accordance with a preferred embodiment, the basic monolith contains about 0.5 wt. % pH modifier, such as sodium carbonate; about 2 wt. % molybdic oxide (MoO.sub.3); about 3 wt. % crude clay; and 75 to 99 wt. % basic refractory aggregate.
Claims9
A basic refractory mix consisting essentially of an amount up to 5 wt. % pH modifier, an amount up to 10 wt. % molybdic oxide, an amount up to 10 wt. % crude clay, and 75 to 99 wt. % of a basic aggregate selected from the group consisting of deadburned magnesite, calcined dolomite, and combinations thereof.
