Metal alkoxides were prepared based on the D. C. Bradley, et al., procedure. Sufficient quantities of princi pally zirconium isopropoxide and tetra-tert butoxide were produced to use as starting material for impregnation and coating purposes. The compounds were prepared by simple chemical reactions but under extremely dry atmosphere. The purity, concentration, order of stability, meltlng temperature, vapor pressure, and decomposition temperature of the compound are described. While the compound may be applicable to coating various materials, to date experiments were limited to coating graphite substrates. The compound was pyrolyzed at 250 to 500 deg C. Tetragonalmonoclinic thin film ZrO/sub 2/ was deposited on graphites of varying purity. (auth)
