Chromium nitrate, with the chemical formula Cr(NO₃)₃, has the CAS number 7789 - 02 - 8. Our high - quality chromium nitrate is produced with strict quality control measures to ensure its purity and stability. The product usually appears as a purple - red crystal. It is soluble in water and ethanol.
The purity of our chromium nitrate can reach over 99%, which meets the high - end requirements of various industries. Its molecular weight is approximately 238.01 g/mol. The density of the solid product is about 1.80 g/cm³. It should be stored in a cool, dry place away from heat sources and incompatible substances such as reducing agents and combustibles.
1. In the field of chemical synthesis, chromium nitrate serves as an important precursor for the preparation of other chromium compounds. It can be used in the synthesis of chromium oxides, which have applications in catalysts, pigments, and magnetic materials.
2. In the electroplating industry, it is used as an additive in chromium plating baths. It helps to improve the quality and appearance of the electroplated layer, enhancing corrosion resistance and hardness.
3. In the analytical chemistry, chromium nitrate is used as a reference standard for the determination of chromium content in various samples. It can also be used in the preparation of calibration solutions for instrumental analysis.
When handling chromium nitrate, proper personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. For chemical synthesis, the appropriate amount of chromium nitrate should be weighed accurately according to the reaction stoichiometry. It is usually dissolved in a suitable solvent, such as water or ethanol, before being added to the reaction system. The reaction conditions, such as temperature, pH, and reaction time, should be carefully controlled to ensure the desired product is obtained.
In the electroplating process, the chromium nitrate should be dissolved in the plating bath according to the recommended concentration. The bath should be well - mixed to ensure uniform distribution of the compound. The electroplating parameters, such as current density, plating time, and bath temperature, should also be optimized to achieve the best plating results.
In analytical chemistry, the chromium nitrate solution should be prepared with high - purity solvents to avoid contamination. The standard solution should be properly stored and used within its expiration date to ensure accurate analytical results.
Case 1: A chemical research institution was working on the synthesis of a new type of chromium - based catalyst. They used our high - quality chromium nitrate as the starting material. By carefully controlling the reaction conditions, they successfully synthesized a highly active catalyst with excellent selectivity. The new catalyst showed improved performance in the oxidation reaction of organic compounds, which led to more efficient production processes and reduced waste.
Case 2: An electroplating company was facing problems with the quality of their chromium - plated products. After switching to our chromium nitrate, they adjusted the plating parameters and found that the appearance and corrosion resistance of the plated parts were significantly improved. The rejection rate of the products decreased from 15% to less than 5%, resulting in cost savings and increased customer satisfaction.
Case 3: A testing laboratory needed to establish a new method for the determination of chromium in environmental samples. They used our chromium nitrate as the reference standard to prepare calibration solutions. The accuracy and precision of their analytical method were improved, allowing them to provide more reliable test results for environmental monitoring.
