The sintering of these aluminosilicate raw materials (clay, andalusite, silica sand, etc.) leads to the synthesis of Mullite (3Al 2 O 3 ·2SiO 2). The mullite is the only stable intermediate phase in the alumina–silica system at atmospheric pressure. ... The cold crushing strength increases as temperature increased to 1400 °C and with ...

This paper demonstrates the latest developments in particle-scale modelling of a clay. It shows that by creating an initial sample of platelets featuring aggregated stacks, excellent macroscopic behaviour is achieved. This approach is justified by examining SEM images of clay slurries, and is consistent with the behaviour of real clays. The use of …

But since it's essentially ground up silica, an ingredient in clay and glaze, adding too much can cause fit uses between the clay body and glaze. Experiment with ratios of sand to clay. Less than 7% sand to clay is a good rule of thumb. Beware of using beach or landscaping sand versus sand purchased from a clay or refractory company.
