Apr 09, 2015· Talc. 2.0. Talc is not a strong flux at cone 6, but for some reason small amounts can have a marked effect on the development of maturity (only 1% can reduce the porosity by 1%). At cone 6 it takes a lot of feldspar to vitrify the body, nearly twice as much as for cone 10.
This requires cordierite ceramics with the greatest possible resistance to temperature changes and a low heat expansion coefficient. This in turn demands talc with a high purity and low CaO content. Finntalc products are flotation purified and tightly controlled for their chemical composition.
Amazingly, talc is also used to produce low expansion ceramics, for example thermal shock resistant stoneware bodies. In these it acts as a low expansion flux that reduces body expansion by converting available quartz mineral, mainly in kaolin, to silicates of magnesia.
