Silica lime is a general term for vein quartz, quartzite, and quartz sandstone.
Silica lime is widely used as a raw material for building materials and an important raw material for the inorganic salt industry. The silica can be processed into a series of silicon compounds by chemical methods. Silica generally refers to high purity natural quartz sand, that is, silica, which is widely distributed in nature and has large reserves. Many countries have large and high-quality mines with large mining volumes.
Mainly used for acid refractory bricks in metallurgical industry. Pure silica can be used as quartz glass or refined single crystal silicon. It is used in the chemical industry to prepare silicon compounds and silicates, and can also be used as a filler in sulfuric acid towers. Used in glass, ceramics, portland cement, etc. in the building materials industry.
Preparation or source: formed by magma hydrothermal or sedimentary.
Sodium silicate and silica are the main products obtained by chemical processing of silica. Sodium silicate is the most versatile and most used product in silica chemical processing products. In addition to being used to manufacture a variety of silicon compounds, it is also widely used as a binder for cardboard, plywood, some metal materials and foundry industries, soap, washing Additives, paper performance improvers, used in textile industry as cotton cloth smelting and bleaching aids, fabric fire-retardant treatment agent, dye color developer. In addition, it is also used as cement coagulant, wood preservative and egg preservative. Sodium silicate can also be used as interior and exterior wall coating after modification. Aluminum silicate can be used as a raw material for glass and ceramics, and can also be used as a paint pigment. Lithium silicate can be used as anticorrosive paint and metal surface protectant.
