Silicates; of sodium (excluding sodium metasilicates)

HS code 283919 covers a range of silicate compounds, primarily those of sodium, excluding sodium metasilicates. These silicates are essential materials in various industries, including glass manufacturing, ceramics, and detergent production. They play a crucial role in the broader chemical industry, contributing to the development of a wide array of products that are integral to modern life.

The production of silicates under HS code 283919 typically involves the reaction of silicon dioxide (SiO2) with sodium compounds, such as sodium hydroxide or sodium carbonate. This process, known as the soda-lime process, results in the formation of various sodium silicate compounds. The specific production techniques may vary depending on the desired end-product, but generally involve controlled heating, mixing, and purification steps to ensure the desired chemical composition and properties.

The main inputs required for the production of silicates under HS code 283919 include silicon dioxide (sand or quartz), sodium compounds (such as sodium hydroxide or sodium carbonate), and energy sources for the heating and processing stages. Additionally, specialized equipment, such as furnaces, mixers, and purification systems, are necessary to ensure the efficient and consistent production of these silicate compounds.

The primary outputs of the industry covered by HS code 283919 are various sodium silicate compounds, which find applications in a wide range of industries. These silicates may be used as raw materials in the production of 701000 Glass and glassware, 692100 Ceramic products, and 340220 Detergents, among others. The specific properties and compositions of the silicates produced can be tailored to meet the unique requirements of these downstream industries.
