The ceramics industry, with its ancient roots and modern innovations, relies on a diverse range of raw materials to achieve desired product characteristics and manufacturing efficiency. Among these, talc, a natural magnesium silicate mineral identified by CAS 13376-74-4, plays a particularly crucial role. Its unique physical and chemical properties, including its softness, thermal stability, and fluxing capabilities, make it an indispensable component in the production of ceramics, refractories, and glazes. As a leading talc manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing high-quality talc that meets the demanding specifications of this sector.

In ceramic bodies, talc primarily functions as a flux. When heated during the firing process, talc breaks down, releasing its magnesium oxide and silica content. This decomposition lowers the melting point of the ceramic formulation, promoting vitrification – the process by which ceramic particles fuse together to form a dense, strong structure. The controlled addition of talc allows for lower firing temperatures or shorter firing cycles, leading to significant energy savings and increased manufacturing efficiency. For ceramic producers looking to optimize their production, buying talc that provides consistent fluxing action is essential.

Furthermore, talc significantly enhances the thermal properties of ceramic products. Its lamellar structure contributes to improved thermal shock resistance, meaning that ceramic items made with talc can withstand rapid temperature changes without cracking or breaking. This property is critical for applications such as kiln furniture, cookware, and sanitaryware. Talc also helps to control the coefficient of thermal expansion of ceramic bodies, reducing shrinkage during firing and minimizing the risk of defects. We offer talc grades that are specifically selected for their contribution to these thermal performance improvements.

Talc is also widely used in ceramic glazes. It acts as a flux, contributing to the melting of the glaze and the development of a smooth, glassy surface. Its presence can influence the viscosity and surface tension of the molten glaze, affecting its flow characteristics and coverage. In addition, talc can help prevent crazing – the network of fine cracks that can appear on glazed surfaces due to differences in thermal expansion between the glaze and the ceramic body. By providing a stable, reliable source of this key mineral, we support ceramic manufacturers in achieving consistent and high-quality glazed finishes.
