Ceramic Bodies With Wollastonite

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.

Ceramic bodies with wollastonite.

The isolation of wollastonite crystals in clay ceramic bodies m. The fibrous form of wollastonite can be very beneficial in bodies. Adlung baykara evo silicatforschung research institute prof. The use of wollastonite fibers having relatively long average fiber lengths as reinforcement agents for unfired sanitaryware bodies.

It also promotes lower moisture and thermal expansion in the fired product and increases firing strength. It was analyzed the technological. In a pure casio 3 each component forms nearly half of the mineral by weight. 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 in ceramic bodies was investigated by analysis of its reactivity with other materials such as quartz kaolin talc and feldspar. 18 89079 ulm germany 1. 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. The additions of sample a wollastonite produced a modification in the fracture behavior of the body resisting crack propagation.

Its use in ceramics depends on the formulation of the ceramic body and the firing method.
