Abstract

A material used for microcrystal glass pump contains nephelinite powder, lepidolite, silica rock powder, alumina, potassium carbonate, magnesium oxide, zirconium oxide, magnesium fluoride, titanium oxide, fluoride, sodium carbonate, boric acid, and composite glass clarifier. Its advantages are high impact toughness and high machinability.

Description

technical field [0001] The present invention relates to a tough, machinable material for glass-ceramic pumps. Background technique [0002] Glass-ceramic is a composite material of the same crystal and glass that was first invented by Corning Glass Company of the United States in 1953, also known as crystal glass. Over the past half a century, the application fields of glass-ceramics have been continuously expanded, and thousands of glass-ceramic products have been released. [0003] In 1996, the present inventor applied for "Technology and Equipment for Using Nepheline to Prepare Glass-Ceramics", Patent No. ZL96115271.0. The core of this patent is to use nepheline instead of precious metal oxides as a nucleating agent, which greatly reduces the raw material cost of glass-ceramics, and improves the mechanical properties and crystallization of glass-ceramics through reasonable formula and improvement of process equipment. speed, thereby increasing the...
