Sodium carboxymethyl cellulose (referred to CMC) is white or yellowish powder, granular or fibrous solid, tasteless, non-toxic, and water soluble. CMC is chosen as the electrolyte in the production of sanitary ceramics, due to its good adhesion, suspension, deagglomeration, and water retention effects.

The application aim is to:
1). act as the binder and play a bonding role. It can increase the strength of raw glaze, reduce the drying shrinkage of glaze, make the green body and the glaze firmly combined and not easy to fall off, be easy for process operation, and prevent such defects as rolling and missing of glaze. While playing the role of suspension, it makes the ceramic slurry suspended and prevents precipitation.
2). play its role of water retention, so that the glaze slurry has a certain water retention and the glaze layer are uniform drying, forming a flat, dense glazed surface and the glazed surface is flat and smooth after firing.
3). use the deagglomeration effects of CMC (of medium and low viscosity) to improve the liquidity of glaze slurry and facilitate the spraying operation of glaze. To achieve the above purposes, it is very important to give full play to the effects of CMC, grasp the properties of CMC and the effects of temperature and time on it, and properly select and apply CMC.
