Kaolin calcium carbonate calcined kaolin clay powder kaolin 97 bt

Product Description
Kaolin calcium carbonate calcined kaolin clay powder kaolin 97 bt has good rheological property and thixotropic property in paint; Increase weatherability, storage stability, brushing property and the calcined kaolin impact resistance.
Kaolin calcium carbonate calcined kaolin clay powder kaolin 97 bt is a powdered white non-plastic material. It is raw kaolin that has been fired (in a rotary calcining kiln) high enough to remove the 12% (approx) crystal water. The material is a good example of how we can alter the mineralogy of a material to affect its working properties while maintaining the chemistry to maintain fired properties.

Kaolin calcium carbonate calcined kaolin clay powder kaolin 97 bt
Kaolin calcium carbonate calcined kaolin clay powder kaolin 97 bt is often under-utilized in traditional ceramics, people do not realize its true value. Kaolin calcium carbonate calcined kaolin clay powder kaolin 97 bt is pure clay mineral, having a fired chemistry of 1 part Al2O3 and 2 parts SiO2. But the raw clay crystals are hydrated, having 12% crystal-bound water. This is the secret to their plasticity. Al2O3 is essential to the chemistry of the vast majority of glazes and kaolin is ideal source material (because all glazes also need the SiO2 that it supplies and it readily decomposes in the melt).
The other principle affordable and readily meltable supplier of Al2O3 are feldspars, however they also supply lots of KNaO (and in many cases oversupply it to get the needed Al2O3). Raw kaolin also supplies suspension to the glaze slurry and it hardens the dry glaze layer. However once raw kaolin percentages pass 20% in a recipe shrinkages can be to high (causing crawling). In these cases substituting part of the raw kaolin for calcined material solves the problem, maintaining the chemistry of the glaze but reducing the shrinkage and cracking.
In other words, by substituting some of the raw kaolin for calcined the physical properties of the glaze slurry can be controlled without impacting the chemistry of the fired melt. Of course, mixing the raw and calcined materials must take into account the LOI of the raw material (12% less calcined is needed).
