Abstract
PURPOSE: To form the thin film of silicon oxide on the surface and to prevent the oxidation evaporation of platinum group metal material under high temperature oxygen atmosphere, by applying and heating organic silicon compound on the surface of the above metal material.
CONSTITUTION: silicic acid ester of organic silicon compound is applied on the surface of platinum group metal material as high temperature heat resisting material and the above metal material is heated at more than 200°C under oxygen contained atmosphere. Hereby, closely adhered silicon oxide thin film is formed at about 5W100μ of thickness on the material surface. After the thin film is formed, each minute crystal of silicon dioxide is sintered well and dense thin film is made by treating with heat at 1300W1600°C for several minutes moreover and preventing effect of oxidation evaporation of platinum group metal material is heightened. The above film is able to easily remove by fluroic acid at the time of recasting etc.
