Silicates; commercial alkali metal silicates

HS v2017 Code: 2839

About silicates; commercial alkali metal silicates

HS code 2839 covers a diverse range of silicate compounds, which are essential materials in various industries. Silicates are salts of silicic acid, and the commercial alkali metal silicates included in this code are widely used as detergents, water softeners, adhesives, and in the production of glass, ceramics, and other construction materials. These versatile compounds play a crucial role in the global economy, supporting a wide range of manufacturing and industrial activities.

Production process

The production of silicates and commercial alkali metal silicates typically involves the reaction of silicon dioxide (SiO2) with alkali metal oxides, such as sodium oxide (Na2O) or potassium oxide (K2O). This process is often carried out at high temperatures, where the silicon dioxide is melted and combined with the alkali metal oxide to form the desired silicate compound. The resulting molten mixture is then cooled and solidified, often into a glassy or crystalline form, before being further processed and distributed for various applications.

Production inputs

The main inputs required for the production of silicates and commercial alkali metal silicates include silicon dioxide (sand or quartz), alkali metal oxides (such as sodium oxide or potassium oxide), and energy sources for the high-temperature reactions. Additionally, specialized equipment, such as furnaces, reactors, and cooling systems, are necessary to facilitate the production process effectively.

Production outputs

The primary outputs of HS code 2839 are a wide range of silicate compounds, including sodium silicate, potassium silicate, and other alkali metal silicates. These materials find applications in numerous industries, including 3214 Glass and glassware, 3207 Paints, varnishes, and related products, 3402 Organic surface-active agents, and 2506 Natural sands. The versatility of silicates makes them essential inputs for a diverse range of manufacturing and construction activities.
