Method of preparing metal oxide fibers

摘要

A method to prepare fibers of nickel oxide and solid solutions of nickel and magnesium oxides by forming a liquid film of a reaction mixture containing at least a nickel salt and a suitable auxiliary salt; reacting the film mixture with water vapor to initiate fibrous growth at a temperature of from about 700 DEG C to 1200 DEG C; continually supplying a film of the mixture over the fibers to sustain growth; and separating the fibers from any residual mixture to thereby produce oxide fibers characterized by a resistance to high temperatures.
