Application

Sodium nitrate is commonly used as a flux in glass production. This helps lower the melting point of the raw materials used to make glass, making it easier to melt and shape into the desired shape. This is especially important for the production of flat glass used in windows, mirrors and other applications. It can also help improve the clarity, color and durability of the glass.
Another important use of sodium nitrate in the glass industry is to decolorize glass. When used in very small quantities, it can help remove unwanted color from glass, making it clear. This is especially important for high-quality optical glass used in cameras, telescopes and other precision instruments.

In steel production, sodium nitrate is used as an oxidizing agent to remove impurities such as sulfur and phosphorus. Its addition helps lower the melting point of impurities, making it easier to remove them from the molten steel. When it reacts with impurities, it forms stable compounds that can be easily removed. This process produces higher quality steel with lower sulfur content.
In the aluminum alloy industry, sodium nitrate is used as a flux to improve casting and smelting processes. Fluxes are used to remove impurities, primarily in the form of oxides. Using it as a flux also helps improve the flow and uniformity of molten aluminum, resulting in a more uniform casting and a higher quality final product.

Another important use of sodium nitrate is as a raw material for the production of bitter acids and dyes. Bitter acids are an essential component in beer production, imparting bitterness and antimicrobial properties. It is used in the production of bitter acids by reaction with plant extracts such as hops.
It is also used in the production of dyes, especially in the textile industry. The compound reacts with various organic compounds to produce a range of vibrant colors. Sodium nitrate is used as a key intermediate in the production of many dyes. It is also used as a color fixative in some textile dyeing processes.
