The Role of CMC in Controlling Drying Shrinkage and Cracking in Ceramics

Carboxymethyl cellulose (CMC) is a widely used binding agent in the ceramics industry. Its ability to control drying shrinkage and prevent cracking makes it an essential component in ceramic formulations. In this article, we will explore the role of CMC in ceramics and how it helps to improve the overall quality of ceramic products.

One of the main challenges in ceramic production is the drying process. As ceramics dry, they undergo shrinkage, which can lead to cracking and warping. CMC acts as a binder in ceramic formulations, helping to control the drying shrinkage and reduce the likelihood of cracking. By forming a strong bond between the ceramic particles, CMC helps to maintain the structural integrity of the ceramic body during the drying process.

In addition to controlling drying shrinkage, CMC also plays a crucial role in improving the workability of ceramic pastes. When mixed with water, CMC forms a viscous solution that helps to bind the ceramic particles together. This results in a smoother, more uniform paste that is easier to shape and mold. By improving the workability of the ceramic paste, CMC helps to ensure that the final product has a consistent and uniform appearance.

Furthermore, CMC also acts as a plasticizer in ceramic formulations. Plasticizers are additives that help to improve the flexibility and workability of ceramic materials. By reducing the viscosity of the ceramic paste, CMC allows for easier shaping and molding of the ceramic body. This results in a more uniform and aesthetically pleasing final product.
