A molding material of a mixture of 0.1-7 wt % of alkali-resistant zirconia glass fibers of 3-25 mm length, 20-60 wt % of wollastonite fibers, and 40-80 wt % of calcium aluminate cement.

Molding material

A fibrous composite material useful in contact with fused aluminum or aluminum alloys is disclosed. The composite material is comprised of alumino silicate-based ceramic fibers, at least one micaceous mineral, an inorganic binder, a dispersant and a plasticizer.

Fibrous composite material for fused aluminum

A method for the insulation of a hot metallic material which is heated for hot working is described, which comprises applying a mixture of acidic aluminum phosphate, e.g., aluminum hydrogenorthophosphate, a multivalent metal oxide, hydroxide, silicate or carbonate powder, and water onto the surface of the hot metallic material and allowing the mixture to be heated by the heat of the hot metallic material to convert it to a porous hardened material. The porous hardened material acts as an insulating coating layer for the hot metallic material, permitting hot working in an insulated state for a long period of time.
