Method of chemically polishing metallic oxides
专利汇可以提供Method of chemically polishing metallic oxides专利检索，专利查询，专利分析的服务。并且A composition for forming a molten salt used as a chemical polishing flux and a polishing sequence employing the flux. In an exemplary embodiment, a method of polishing a metallic oxide substrate comprises the steps of forming a molten flux from approximately a 30:1 to 50:1 weight ratio of lead monoxide and boric anhydride at a temperature within the approximate range 1,100*-1,200*C; bringing the flux to thermal equilibrium at a predetermined temperature suitable for establishing a desired rate of dissolution of the substrate material; moving the substrate at a controlled rate toward the molten flux; and immersing the substrate in the molten flux for a sufficient time to strip a predetermined thickness of material from the surfaces of the substrate. The dissolution rate may be varied by changing the temperature of the flux and/or by adding one or more constituents to the flux to vary the saturation point thereof. A controlled rate of withdrawal of the substrate from the flux may be used to form a protective coating on the stripped substrate surfaces. Because the coating can be removed by compatible liquid phase epitaxy systems, liquid phase epitaxy maybe used to grow films on the substrate without intermediate cleaning steps. Alternatively, the flux may be formed by combining boric anhydride (B2O3) with one or more of lead monoxide (PbO), lead fluoride (PbF2), barium oxide (BaO) barium fluoride (BaF2), iron oxide (Fe2O3), vanadium pentoxide (V2O5) and lithium carbonate (Li2CO3).，下面是Method of chemically polishing metallic oxides专利的具体信息内容。
