Ceramic bodies with wollastonite.

The fibrous form of wollastonite can be very beneficial in bodies. The isolation of wollastonite crystals in clay ceramic bodies m. The use of wollastonite in ceramic bodies was investigated by analysis of its reactivity with other materials such as quartz kaolin talc and feldspar. In ceramics wollastonite competes with carbonates feldspar lime and silica as a source of calcium and silicon.

It was analyzed the technological. In low fired ceramics wollastonite reduces drying and firing shrinkage and drying and firing warpage. The use of wollastonite fibers having relatively long average fiber lengths as reinforcement agents for unfired sanitaryware bodies. As table 2 demonstrates multiple tests were conducted on unfired ceramic bodies containing varying amounts of sample a wollastonite in the preferred range from about 1 to about 7 by dry weight.

Aim of the work in the field of building ceramics as well as for the testing of materials containing chalk the system si02 ai203 cao is very important for practice. 18 89079 ulm germany 1. Its use in ceramics depends on the formulation of the ceramic body and the firing method. The addition of refined wollastonite to sanitaryware bodies exhibited improved resistance to propagation of cracks reduced drying and firing shrinkage fluxing activity an hf release inhibition upon firing.

In a pure casio 3 each component forms nearly half of the mineral by weight.
