Chemical properties of transparent quartz glass
2018-12-25 15:49
Transparent quartz glass is an acidic material, so it is an excellent acid-resistant material. Except for HF and hot phosphoric acid, any concentration of organic and inorganic acids, even at high temperatures, can hardly corrode transparent quartz glass. As an acid-resistant material, transparent quartz glass is better than all acid-resistant metals and alloys, and is also better than general organic acid-resistant materials. The acid resistance of transparent quartz glass is 1 to 3 times higher than that of opaque quartz glass.
Quartz glass has poor resistance to the chemical action of alkalis and alkaline salts. This is because it can generate soluble silicates. Therefore, quartz glass is not suitable for use in strong alkaline media.
Since quartz glass is an excellent acid-resistant material, it has been widely used in chemical laboratories, and sometimes it can even partially replace glassware. Quartz glass is used as an acid-resistant material in the Ministry of Chemical Industry to manufacture acid-resistant equipment and glass containers.
