Colemanite is a calcium borate mineral with the chemical formula Ca₂B₆O₁₁·5H₂O. It has a CAS number of 1318 - 33 - 8. This mineral is commonly found in evaporite deposits and is an important source of boron. Colemanite typically occurs as colorless, white, or sometimes pale yellow or blue crystals. It has a Mohs hardness of around 4.5, which means it is relatively soft. The specific gravity of colemanite is approximately 2.42. It is insoluble in water but can react with acids to release boric acid.
Our factory - supplied colemanite is of high purity, ensuring that it meets the strict requirements of various industries. We offer it at a competitive price, making it an economical choice for our customers.
Colemanite has a wide range of applications across different industries:
Glass and Ceramics Production: In the glass and ceramics industry, colemanite is usually added to the batch mixture during the melting process. The amount of colemanite added depends on the specific requirements of the product. It is recommended to start with a small amount and gradually adjust according to the test results. The colemanite should be well - mixed with other raw materials to ensure uniform distribution.
Metalurgia: In metallurgical applications, colemanite can be added directly to the molten metal. It is important to ensure that the addition is made carefully to avoid splashing. The reaction time and temperature should be controlled to achieve the best results.
Agricultura: For agricultural use, colemanite can be applied as a soil amendment. It should be evenly spread over the soil surface and then incorporated into the soil by tilling. The application rate depends on the soil type, crop type, and boron deficiency level. It is advisable to conduct a soil test before application to determine the appropriate dosage.
Flame Retardant: When using colemanite as a flame - retardant additive, it should be mixed with the base material during the manufacturing process. The mixing ratio should be optimized according to the desired flame - retardant performance and the properties of the base material.
Glass Manufacturer: A glass manufacturer in Europe was facing high energy costs due to the high melting point of their raw materials. They decided to use our factory - supplied colemanite as a flux. After adding colemanite to their batch mixture, they noticed a significant reduction in the melting temperature. This led to a 20% decrease in energy consumption during the glass - making process. The final glass products also had better clarity and thermal shock resistance, which improved their market competitiveness.
Agricultural Farm: A farm in South America was experiencing poor crop yields due to boron deficiency in the soil. They applied colemanite - based fertilizers to their fields. After a growing season, they observed a 30% increase in crop yields. The fruits were larger and of better quality, which resulted in higher profits for the farm.
