MAGNESIUM OXIDE IN FIBER FORM BY EXTRUSION METHODS

摘要

A technique is described for forming "filaments" of aggregated magnesium ©and© particles by extrusion of magnesium oxide dispersed in a majttesiurr ac©ta4,e-nethanol-water system, Theie "filaments" can be converted to thermally-stable, hollow "fibers" by heating or by hydrolysis. The thermal insulating properties of this material equal or exceed these of magnesium oxide powder, and the initial poor strength and brittleness can be improved some-what by subsequent chemical or physical treatment.
