Sodium bromate (NaBrO3) (link:https://www.bloomtechz.com/synthetic-chemical/sodium-bromate-powder-cas-7789-38-0.html) is a colorless or white crystal that exists in the form of colorless or white crystals, usually in the form of lumps or granules. It has good solubility in water, it can dissolve quickly and produce proton exchange reaction. Its solubility increases with temperature. The crystal structure belongs to the orthorhombic crystal system. The lattice parameters are a=7.713 Å, b=5.442 Å, and c=6.496 Å. Each Na+ ion is surrounded by eight oxygen atoms, and each BrO3- ion is adjacent to six sodium ions. It is relatively stable at room temperature, but will decompose under high temperature or heating conditions to generate sodium chloride and oxygen. It has strong oxidizing and bleaching properties and can oxidatively destroy various organic pigments to achieve bleaching of items. It is widely used in the bleaching process of paper, textile, leather, wood and other industries.

4. Water treatment agent:
Sodium bromate can be used in the water treatment process to remove harmful substances in the water, such as heavy metal ions, organic pollutants, etc. Through oxidation, it can decompose organic pollutants in the water, and at the same time play sterilization, deodorization and other functions.
In the field of water treatment, Sodium bromate can be used to remove organic pollutants and heavy metal ions in water. Through its oxidation effect, it can break down organic pollutants in water and convert them into harmless or low-toxic substances. In addition, Sodium bromate can also play a role in sterilization and deodorization, improving water quality and improving water safety. This application is of great significance in fields such as industrial wastewater treatment and drinking water treatment.
5. Match manufacturing: Sodium bromate is one of the important raw materials for making matches. Together with potassium chlorate and other substances, it is the main component of match powder and can produce a frictional ignition reaction to make matches burn.
In the match manufacturing process, Sodium bromate is one of the main ingredients of match powder. It is mixed with substances such as potassium chlorate, and when rubbed against a match head, it can produce a frictional ignition reaction and ignite the match. This is safer and more environmentally friendly than traditional sulfur and potassium chlorate matches.
6. Explosives preparation: In the preparation process of some explosives, Sodium bromate can be used as an oxidant to provide the necessary energy and the oxidizing environment required for the reaction. After it is mixed with organic matter, it can be made into a variety of explosives, such as TNT, RDX, etc.
In the preparation process of explosives, Sodium bromate can be used as an oxidant to provide necessary energy and oxidizing environment for explosives. For example, it can be mixed with organic matter to make a variety of explosives, such as TNT, RDX, etc. These explosives are widely used in military, mining and blasting engineering fields.
7. Glass making: When making glass, Sodium bromate can be added to the glass melt as a clarifier to help remove impurities and bubbles in the glass and improve the quality and transparency of the glass.
In the glass manufacturing process, Sodium bromate can be added to the glass melt as a clarifier. It can react with impurities in the glass to generate low-density bubbles, thereby helping to remove bubbles and impurities in the glass and improve the transparency and quality of the glass. This application is widely used in architectural glass, automotive glass and other fields.
8. Agricultural application: In the agricultural field, Sodium bromate can be used as a plant growth regulator. It promotes plant growth, increases yield and improves quality. However, it is important to note that overuse of Sodium bromate may have negative effects on plants and the soil environment.
9. Environmental monitoring: Sodium bromate is also used in the field of environmental monitoring. It can be used as a tracer to study the migration and transformation of pollutants in water bodies. At the same time, by detecting the consumption of sodium bromate in the water body, the self-purification ability of the water body can be evaluated.
Sodium bromate is used as a tracer in the field of environmental monitoring, which can effectively track and understand the migration and transformation rules of pollutants in water bodies. By detecting its consumption, researchers can understand the self-purification ability of water bodies, thereby providing valuable information for environmental protection and water resources management. This application helps assess the health status of water bodies and take appropriate measures to protect water resources.
10. Medical applications: In the medical field, Sodium bromate is used as a contrast agent to enhance the clarity and contrast of medical images. It is also being studied as a candidate material for radioactive tracers for medical diagnosis and treatment.
