Ceramic Bodies With Wollastonite

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.

Ceramic bodies with wollastonite. The fibrous form of wollastonite can be very beneficial in bodies. 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. The use of wollastonite fibers having relatively long average fiber lengths as reinforcement agents for unfired sanitaryware bodies. In ceramics wollastonite competes with carbonates feldspar lime and silica as a source of calcium and silicon.

48 3 of cao and 51 7 of sio 2. Adlung baykara evo silicatforschung research institute prof. It was analyzed the technological. In low fired ceramics wollastonite reduces drying and firing shrinkage and drying and firing warpage.

The isolation of wollastonite crystals in clay ceramic bodies m. 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. In a pure casio 3 each component forms nearly half of the mineral by weight. Its use in ceramics depends on the formulation of the ceramic body and the firing method.

It also promotes lower moisture and thermal expansion in the fired product and increases firing strength.
