Silicates; commercial alkali metal silicates, other than of sodium

HS code 283990 covers a diverse range of silicate compounds, excluding those of sodium. These silicates have a wide array of industrial applications, serving as essential raw materials in the production of glass, ceramics, cement, and various chemical products. They play a crucial role in the construction, manufacturing, and environmental sectors, contributing to the development of sustainable technologies and infrastructure.

The production of commercial alkali metal silicates, other than sodium, typically involves the reaction of silicon dioxide (SiO2) with various alkali metal oxides, such as potassium oxide (K2O) or lithium oxide (Li2O). This process is often carried out in high-temperature furnaces or reactors, where the raw materials are melted and combined to form the desired silicate compounds. The resulting molten mixture is then cooled and solidified, often into granular or powdered forms, ready for further processing or direct use in various applications.

The main inputs required for the production of HS code 283990 silicates include silicon dioxide (SiO2) as the primary raw material, as well as various alkali metal oxides, such as potassium oxide (K2O) or lithium oxide (Li2O). Additionally, the production process may require specialized equipment, such as high-temperature furnaces, reactors, and cooling systems, as well as energy sources to power the manufacturing operations.

The silicates produced under HS code 283990 have a wide range of applications, including the manufacture of 681100 glass products, 691000 ceramic products, 252300 cement, and various chemical products. These silicates are also used in the production of 282000 other inorganic chemicals, 284000 radioactive chemical elements and isotopes, and 285000 other inorganic bases and metal oxides, hydroxides and peroxides, among other industries.
