Ceramic Grade CMC
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.

(2% Soln. Brookfield SVR)
Remark: Can customize the viscosity and purity of products as per your
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.
