Ceramic slurry is obtained by mixing ceramic powder, carrying vehicle, binder, and dispersant to produce uniformly dispersed ceramic slurry. It is important to optimize the slurry composition in order to obtain high green density, low green shrinkage, and sufficient green strength to produce defect-free demolding. Dispersant is used to separate the agglomerated particles in a slurry by controlling the

Liquid dispersion of ceramic powders sometimes is used to make slurries. Slurry processing facilitates mixing and minimizes particle agglomeration. The primary disadvantage of slurry processing is that the liquid must be removed prior to firing the ceramic. Dry powders often are granulated to improve flow, handling, packing, and compaction.
Need To Use Ceramic Powder Materials For Thermal Spray Applications? When it comes to manufacturing industrial equipment and related components, the use of advanced ceramic powders such as white alumina ceramic powder (suited for plasma spraying) is a must. In todays times, performance and efficiency standards are constantly rising.
