Production of inorganic fibres

Abstract From the Canadian patent

A process for the production of inorganic fibers from a liquid medium. A solution dispersion, or sol containing one or more fiber-forming compounds is dry spun into an evaporative environment. The compounds are selected from the group consisting of nitrates carbonates, sulfates, acetates, oxalates chlorides and oxychlorides. In the case of sol the sol is selected from hydroxide sols, oxide sols, phosphate sols silicate sols, borate sols, tungstate sols and molybdate sols which upon heating yield an oxide carbide, or nitride. The above compounds are compounds of elements selected from the group consisting of Be, Mg, Ca, Sr, Ba Th, U, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W Fe, Co, Ni, Zn, B, Al, …
