PROCESS FOR THE PREPARATION OF MAGNESIUM OXIDE FILMS USING ORGANOMAGNESIUM COMPOUNDS

摘要

A process for coating the surface of a single crystal with a magnesium oxide film which comprises contacting an organomagnesium compound having an oxygen to magnesium atomic ratio of 1:1 with the crystal heated to a temperature ranging from 300 ~C to 450 ~C in the absence of oxygen. The magnesium oxide film thus produced has a negligible amount of residual carbon.
