Classification and Performance Comparison of Medicinal Glass at Home and Abroad
China divides medicinal glass into four categories (high boron, medium boron, low boron, and sodium calcium) based on its composition and properties. The main indicators are the content of silicon trioxide and the average coefficient of thermal expansion; According to the water resistance of glass in Europe and America, glass is divided into four categories (I, II, III, IV), with the main indicators being surface water resistance, water resistance of glass particles, and water resistance of etched glass.
