It is a water-soluble polymer made by chemically modifying natural cellulose. Ceramic grade CMC is commonly used in the production of ceramic products, such as tiles, tableware, and sanitary ware, to improve the mechanical properties and workability of the ceramic materials.
Ceramic grade CMC has several properties that make it ideal for use in the ceramic industry. include:
High viscosity: Ceramic grade CMC has a high viscosity, which helps to improve the workability of ceramic materials and reduce the amount of water needed for processing.
Good dispersion: Ceramic grade CMC disperses easily in water, which allows for a more uniform distribution throughout the ceramic material and improves the consistency of the final product.
Strong adhesion: Ceramic grade CMC has strong adhesive properties, which helps to improve the bonding between ceramic particles and reduce cracking and deformation during processing.
Good rheology control: Ceramic grade CMC can be used to control the rheology of ceramic slurries, which improves the stability and flow properties of the material during processing.

As a type of CMC sodium carboxymethyl cellulose, ceramic grade carboxymethyl cellulose (CMC) is commonly used in the ceramic industry to improve the workability, mechanical properties, and efficiency of ceramic materials. Here are some general guidelines for using Creamic Grade CMC:
Determine the appropriate dosage: The optimal dosage of Creamic Grade CMC depends on the specific application and desired properties. Typically, dosage levels range from 0.1% to 1.0% by weight of the ceramic material.
Prepare the ceramic slurry: Creamic Grade CMC is typically added to the ceramic slurry during the mixing process. The slurry should be prepared according to standard industry procedures, and the CMC should be added slowly and evenly while stirring.
Mix thoroughly: After adding the Creamic Grade CMC, the slurry should be mixed thoroughly to ensure that the CMC is evenly distributed throughout the material.
Adjust the rheology: If necessary, the rheology of the ceramic slurry can be adjusted by adding more or less CMC. Rheology modifiers such as deflocculants or dispersants may also be added to achieve the desired rheology.
Process the material: After the ceramic slurry has been prepared, it can be processed according to standard industry procedures, such as casting, pressing, or extrusion.
Test the final product: After processing, the final product should be tested to ensure that it meets the desired properties and performance criteria.
