Ceramic Bodies With Wollastonite

The isolation of wollastonite crystals in clay ceramic bodies m.

Ceramic bodies with wollastonite.

It also promotes lower moisture and thermal expansion in the fired product and increases firing strength. In low fired ceramics wollastonite reduces drying and firing shrinkage and drying and firing warpage. Its use in ceramics depends on the formulation of the ceramic body and the firing method. 18 89079 ulm germany 1.

The fibrous form of wollastonite can be very beneficial in bodies. The use of wollastonite fibers having relatively long average fiber lengths as reinforcement agents for unfired sanitaryware bodies. 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.

48 3 of cao and 51 7 of sio 2. 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 use of wollastonite in ceramic bodies was investigated by analysis of its reactivity with other materials such as quartz kaolin talc and feldspar. It was analyzed the technological.

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.
