Sodium carboxymethyl cellulose (CMC), as a hydrophilic colloid, has good hydrophilicity and can form a stable network structure in water after being dissolved in water. It is used as an excipient and plasticizer in ceramic body. It is used in the billet body to enhance the bonding force of the billet, make it easy to form, improve stability, and improve the rate of excellent ceramic products. Used in ceramic glaze, make the glaze, stable dispersion state, improve the surface tension of the glaze, increase the leveling, reduce the pinhole phenomenon of the glaze after sintering;

The application characteristics of sodium carboxymethyl cellulose (CMC) in ceramics:

1. Enhance ligand molding, improve embryo strength and stability;

2. Improve leveling and reduce enamel sintering pinholes;

3. Improve the surface tension of the glaze and enhance the smoothness of the glaze;
