Applications:

1. Ceramic Coating for Lithium-ion Battery Separators

Orifice Adjustment and Current Interruption Protection: Utilizing its plate-like crystal structure, it expands in volume when the current is too high or the temperature rises, closing the current conduction orifices of the separator, blocking the current, and improving safety.

Enhanced Thermal Stability: It has excellent heat resistance, improving the deformation stability of polyolefin (PP/PE) separators at high temperatures, preventing large-area short circuits caused by separator shrinkage.

Thermal Conductivity and Dissipation: It improves the poor thermal conductivity of the separator, assisting in the conduction of heat inside the battery and reducing the risk of thermal runaway.

 

2. Edge Coating for Lithium-ion Battery Electrodes

Burry Coverage and Insulation: Specifically coated on the edges of the positive electrode, utilizing its slightly soft texture and good dispersibility, it effectively covers burrs generated during cutting, preventing puncture of the separator and improving battery assembly yield.

Tool Protection: Compared to traditional alumina, it causes less damage to cutting tools.

 

3. High-Performance Inorganic Flame Retardant Synergist

Endothermic Decomposition: Decomposes endothermally upon heating, releasing water of crystallization, diluting flammable gases and eliminating smoke.

Wide Compatibility: Commonly used in wires and cables, high-temperature nylon, and various engineering plastics, significantly improving the flame retardancy rating of materials without producing toxic gases.

 

4. Copper Clad Laminate and Electronic Substrate Filler

Heat Resistance and Flame Retardancy: Used as a filler in electronic substrates, it significantly improves the heat resistance, yield, and flame retardancy of circuit boards.

 

5. High-Performance Coating Additive

Physical Protection: Plate-like crystalline particles prevent fluid intrusion and gas permeation, improving the coating's moisture resistance, water resistance, and aging resistance.

 

6. Catalyst and Carrier

Precursor Application: As a core precursor for the preparation of activated alumina (α-AlOOH), the calcined product exhibits extremely high catalytic activity and selectivity.

 

7. Advanced Paper Filler

Functional Filler: Used in newspapers, banknote paper, photographic paper, etc., possessing better surface properties and adsorption than ordinary fillers.

 

8. Artificial Marble and Agate Filler

Optical Effects: Its refractive index is close to that of polyester resin, giving the finished product extremely high light visibility (transparency), and it is lightweight and resistant to cracking.

 

9. Rubber and Plastic Reinforcement

Mechanical Enhancement: The micro-plate-like crystals can significantly improve the tensile strength, tear strength, and reinforcing properties of the product, while also providing resistance to seawater corrosion.
