Ceramic Bodies With Wollastonite

The fibrous form of wollastonite can be very beneficial in bodies.

Ceramic bodies with wollastonite.

Adlung baykara evo silicatforschung research institute prof. Its use in ceramics depends on the formulation of the ceramic body and the firing method. 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. The isolation of wollastonite crystals in clay ceramic bodies m.

It was analyzed the technological. In a pure casio 3 each component forms nearly half of the mineral by weight. 48 3 of cao and 51 7 of sio 2. 18 89079 ulm germany 1.

The additions of sample a wollastonite produced a modification in the fracture behavior of the body resisting crack propagation. 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 low fired ceramics wollastonite reduces drying and firing shrinkage and drying and firing warpage. It also promotes lower moisture and thermal expansion in the fired product and increases firing strength.

The use of wollastonite fibers having relatively long average fiber lengths as reinforcement agents for unfired sanitaryware bodies.
