What is ceramic shell made of? Introduction. Ceramic shell moulds in investment casting is essentially compromised of ceramic stuccos, ceramic filler and binder usually made from ceramic colloidal sol.

How is ceramic slurry made?
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.
Are oysters killed for pearls?
