Uses:
1.Refractory materials Adding pyrophyllite to refractory bricks or refractory materials can form a SiO2-rich mullite phase, which forms secondary mulliteization during use. The resulting volume expansion offsets the shrinkage of the material and improves the volume stability of the material .
2. Ceramics field (1) Building and sanitary ceramics (2) Dielectric ceramics Pyrophyllite has insulating properties and can be used as a raw material for the preparation of dielectric ceramics. (3) Acid-resistant ceramics (4) Ceramic abrasive tools
3. Pressure transmission and sealing medium Pyrophyllite is widely used as a pressure transmission and sealing medium in high pressure synthesis industries such as synthetic diamond and cubic boron nitride due to its good pressure transmission, heat insulation, sealing, machining and insulation characteristics.
4. Glass fiber
5. Rubber field 6. The field of adsorbents 7. Flame retardant
