For the field of ceramic high heat resistance we have 2 types of clay compositions:
- High alumina clays, which support high cooking temperatures and confer plasticity to the bodies with high percentage of aggregates.
Their Fe2O3 content varies between 2% and 8%. They are suitable for calcining and obtain high quality chamottes.
- Clays high quartz content, with a high silica/alumina ratio and low in iron oxide and other fluxes. These are perfect for regulating expansion coefficients of bodies suffering from long cooking cycles and high temperatures.
In all cases, wide reserves of clay permit us adapt to the needs of our customers with a guarantee of long life.
