Ceramic Bodies With Wollastonite

In low fired ceramics wollastonite reduces drying and firing shrinkage and drying and firing warpage.

Ceramic bodies with wollastonite.

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. The additions of sample a wollastonite produced a modification in the fracture behavior of the body resisting crack propagation. In a pure casio 3 each component forms nearly half of the mineral by weight.

It was analyzed the technological. 48 3 of cao and 51 7 of sio 2. It also promotes lower moisture and thermal expansion in the fired product and increases firing strength. 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. Adlung baykara evo silicatforschung research institute prof. 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.

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