Clay
Product Benefits
The properties of ball clays are down to their relatively high content of colloidal and organic matter.
UK clays
- rheological stability
- unfired strength
- plasticity
- workability
Ukrainian clays
- Higher bending strength on both green and dried stage
- White-fired colour
- Low level of organic matter that allows fast firing cycle
- High fusibility features, that can reduce the final porosity of ceramic body and increase the speed of the firing cycle with natural gas saving and more production yield
German clays
- Low level of organic matter that allows fast firing cycle
- Stable product along supplies which support the stability of production process
- Good logistic network and supply chain: truck, train, barge and vessel
Russian clay
- High Allumina clay with good plasticity
- White firing colour
- Stable product along supplies that support the stability of production process
