Mainly used as additives in industries such as alumina ceramics, silicon nitride ceramics, silicon carbide ceramics, zirconia ceramics, magnetic materials, electronic ceramics, magnesium-made ceramics, and daily-use ceramics. Add TC-421 to the grinding process The dispersant can greatly reduce the viscosity of the processed material and facilitate the processing of the material, and the slurry viscosity is stable after dispersion, and the slurry viscosity stability is good at different temperatures and pHs. TC-421 ceramic dispersant all volatilizes during the product baking process, which has no effect on the physical and chemical properties of the product.
