METHOD OF PRODUCING CRYSTALLIZED GLASS-CERAMICS DENTAL COMPOSITION

摘要

The present invention provides a manufacturing method for dental crystallized glass-ceramics, with excellent aesthetic properties and excellent mechanical properties. According to the present invention, the manufacture of the dental glass-ceramics has a manufacturing process using a platinum stirrer for manufacturing a high-refining glass without bubbles while using a platinum crucible for manufacturing a high-purity glass. Particularly, a continuous-type heat treatment manufacturing process is capable of manufacturing glass-ceramics with high productivity and small deviation of material properties, which continuously performs slow cooling and crystallized heat treatment until reaching room temperature without cooling after molding a glass, in comparison with a generally performed and complicated process of elevated temperature and crystallized heat treatment for heat treatment of slow cooling, cooling until reaching room temperature, and crystallization after molding a glass.
