Ceramic bodies with wollastonite.
It was analyzed the technological.
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.
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.
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.
It also promotes lower moisture and thermal expansion in the fired product and increases firing strength.
In ceramics wollastonite competes with carbonates feldspar lime and silica as a source of calcium and silicon.
In low fired ceramics wollastonite reduces drying and firing shrinkage and drying and firing warpage.
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.
