Abstract
The invention relates to an opal glaze formula for trical ceramics. The opal glaze comprises the following components in parts by weight: 41-43 parts of chinastone, 17-21 parts of zircon sand, 6-7 parts of aluminum oxide, 10-12 parts of talc, 4-8 parts of construction oil, 3-5 parts of calcium fluoride, 5-6 parts of barium carbonate and 16-18 parts of opacifier. The high-strength electrical ceramic glaze prepared by adopting the formula is high in whiteness, high in breaking strength, good in cold and hot surging resistance and stable in performance and is applied to various electricity industries.
Description
Technical field
The present invention relates to electroceramics technical field, more specifically, relate to a kind of opal glaze for electric porcelain formula.
