Application

Kaolinite can be used:
  • In the preparation of of polysialate polymers.
  • To prepare mullite composites by sintering kaolinite and alumina.
  • To synthesize microporous materials such as zeolite Linde Type A (LTA) and kaoline based silicoaluminophosphate (SAPO) molecular sieves.
  • In the synthesis of terbium pyridine-picolinate grafted kaoline, as a luminescent hybrid material.
  • As a filler and a coating pigment in the paper industry.
