Tableware bodies Imerys wollastonites - cost-effective, low LOI fluxing agents and reinforcing minerals for tableware bodies
Imerys wollastonites are cost-effective, low loss on ignition (LOI) natural fluxing agents in white body earthenware and porcelain pottery dinnerware, where they improve mechanical properties and surface finish of fired bodies. Imerys wollastonites contribute CaO to the ceramic formula without outgassing, allowing manufacturers to reduce firing temperatures and time compared to traditional materials, generating cost savings and lowering CO2 emissions.
Tableware body processing
Used in tableware processing, Imerys acicular wollastonites are excellent, low LOI replacements for other calcium oxide sources.
Added to unfired, green bodies, wollastonite:
- Reduces firing temperatures and firing cycles, facilitating fast firing and lowering energy consumption and CO2 emissions
- Reduces firing shrinkage
- Increases green and fired toughness
- Enhances impact strength
- Improves thermal stability preventing thermal shock
- Speeds up drying times
