Calcite Powder For Industrial

Calcite Powder is a grounded calcium carbonate powder made from limestone mineral. It has various applications in glass, ceramic, paint, rubber, and other industries. Calcite Powder or Limestone is a common sedimentary rock composed primarily of the calcium carbonate mineral, calcite (CaCO3). Calcite Powder constitutes approximately 10 percent of the sedimentary rocks exposed on the earth's surface. Limestone frequently also contains the minerals dolomite or calcium magnesium carbonate (CaMg(CO3)2, and a second crystalline form of calcium carbonate, aragonite.
Calcium carbonate is used as a filler to improve the physical properties of ceramic products. It helps to reduce production costs by replacing more expensive materials and extending the raw material supply. By incorporating calcium carbonate into the ceramic matrix, manufacturers can achieve better control over the product’s density, strength, and dimensional stability. Calcium carbonate is an excellent whitening agent, which is highly desirable for many ceramic applications. It improves the opacity and brightness of ceramic products, giving them a clean, white appearance. This property is particularly important for ceramic items such as sanitaryware, tiles, and dinnerware, where a bright and attractive finish is desired.
Calcium carbonate is often used in ceramic glazes to adjust their viscosity and control their flow during application. It acts as a suspending agent, preventing the settling of solid particles in the glaze mixture. This ensures an even and consistent coating on the ceramic surface, enhancing the final appearance of the glazed product. Calcium carbonate exhibits good thermal stability, making it suitable for high-temperature ceramic processes. It can withstand the firing temperatures required for ceramic production without undergoing significant decomposition or phase changes Incorporating calcium carbonate into ceramic formulations can help reduce the shrinkage of the final product during firing. This is particularly important for applications where precise dimensions and minimal distortion are crucial, such as in architectural ceramics or electronic components. calcium finds extensive use in the ceramic industry as a filler material, contributing to improved physical properties, opacity, and whiteness of ceramic products. Its ability to adjust viscosity, thermal stability, and environmental friendliness make it a versatile and valuable additive for various ceramic applications
