Title:
COATING METHOD WITH SILICA-BASED GLASS
Document Type and Number:
Japanese Patent JPS6475683
Kind Code:
A
Abstract:
PURPOSE: To form a coating film of silica-based glass having superior consistency by putting solid silicon near a body to be coated and heating the silicon in a reducing atmosphere contg. steam.
CONSTITUTION: Paste or the like contg. solid silicon is put near a body to be coated. It is heated in a reducing atmosphere of hydrogen or other gas contg. steam to form a coating film of silica-based glass on the body to be coated. The concn. of steam in the reducing atmosphere is desirably regulated so that the atmosphere has -30W25°C dew point. Thus, a coating film free from cracks can be formed. This method is applicable to a heat and corrosion resistant insulated cable for communication or for a heater, a heat resistant reflecting mirror, etc.
