This is the difficult and hot subject in the kaolin trade.

Porcelain stone and kaolin have different ingredients and origins so that they have different methods of quarrying and processing.

The toughening of PP-kaolin composite by method of combining chemical and physical modifications in processing apparatus was studied in this paper.

The XRD of different specimens showed that there were a series of phase transitions with the different roast temperature of kaolin.

The tests that the viscosity of kaolin slurry influenced by dispersants solely are carried at the concentration of 63% and 68% respectively.
