Abstract
A refractory composition comprises a basic refractory raw material such as oxides or hydroxides of magnesium, calcium, chromium or maganese, quaternary ammonium hydroxide and silica sol and/or silicate. The composition is used to prepare unfired refractories having a high compression strength by merely molding and drying it without the necessity of firing. When fired, it manifests comparable compression strength. The composition can also be used as monolithic refractory, refractory mortar, refractory coating agent, mold release, etc.
