What is Kaolin?

 · The primary constituent in kaolin is the mineral kaolinite, a hydrous aluminum silicate formed by the decomposition of minerals such as feldspar. The name kaolin derives from the Chinese and means high ridge. High ridge is a reference to the hill in south-eastern China where the clay was originally discovered and used.

The effect of pH and temperature on kaolinite dissolution

Steady-state kaolinite dissolution rates were examined using non-mixed flow-through reactors. The experiments were conducted at 25°C, 50°C and 70°C in a pH range of to at far-from equilibrium conditions ( < D G r < -39 kcal mol-1). It was found that kaolinite dissolution rate increases with temperature and decreases with pH.
