Strontium hydroxide is primarily used in the refining of beet sugar, where it plays a crucial role in the purification process. It helps to remove impurities and non-sugar substances, ensuring a higher quality of the final sugar product. Additionally, it is employed in the production of strontium lubricants, which are essential for certain industrial applications due to their ability to withstand high temperatures and pressures. In the field of electronics, strontium hydroxide is utilized in the manufacture of cathode ray tubes (CRTs) and other glass components, where it contributes to the desired optical properties. It also finds use in the preparation of various strontium compounds, which are applied in pyrotechnics to produce bright red flames. Furthermore, it serves as a precursor in the synthesis of strontium carbonate, a compound widely used in the ceramics and glass industries.
