1.Application in ceramic body
CMC belongs to polyelectrolytes. It worked as binder and played a role of suspending. When CMC is added into glaze pulp, water seeped into the gel inside, and then its hydrophilic radical combined with water, and makes it swell. In addition, the gel inside is in the hydration swelling conditions, while its outside forms the bound water layer. The micelle is free in the liquid cement at the first dissolution and due to the different and asymmetric size and form, and regularly close up to each other through the Van der Waals forces and then combined with water layer to form the large size network structure, so it has the stronger adhesive capacity.
3.Application in ceramic decalcomania
Penetration glaze contains a lot of soluble salt matter with partial acid property. CMC which used in penetration glaze has the excellent stability of acid resistance, salt resistance, and keep the viscosity stable in use or storage, and avoid the chromatic aberration caused by viscosity change, so it greatly improve the stability of the penetration glaze.

When CMC, the unique linear polymers structure, is in the water, its hydrophilic radical combined with water and become the solvation layer and make the CMC molecule be dispersed gradually in the water. CMC high polymers become the network structure supporting by the hydrogen bond and Van der Waals forces, where the bond property is shown. Ceramic body CMC works as the excipient, plasticizer and intensifier in ceramic industry.

2. Application in glazing pulp

CMC, with good solubility and high transparency of the solution, as well as no residue, possesses the excellent shear-thinning and lubrication, and greatly enhance the decalcomania adaptability.
