Applications of Benzophenone

1. Lithium Battery Industry: Ceramic coating for Li-ion battery separator & electrode coating (EV power battery, energy storage battery, LFP battery mainstream coating material)

2. Catalyst Industry: Precursor of activated alumina, catalyst carrier for petrochemical refining, automobile three-way catalyst, molecular sieve raw material

3. Advanced Ceramics: High-purity transparent alumina ceramic, electronic ceramic, phosphor substrate, refractory raw material

4. Functional Additive: Halogen-free flame retardant for plastic/rubber, polishing powder, adsorbent for wastewater treatment

Core Product Advantages

1. Low Mohs Hardness(3~3.5): Less abrasion to coating equipment vs fused alumina, ideal for lithium separator ceramic coating

2. High thermal stability(Decompose≥450℃): Flame retardant & heat-resistant, upgrade lithium battery thermal safety, prevent separator thermal shrinkage

3. Rich surface hydroxyl & adjustable specific surface area(30~300m²/g): Perfect carrier for petrochemical/auto exhaust catalyst loading precious metal(Pt/Pd)

4. Low water absorption, good electrolyte wettability: Improve lithium ion permeability, extend battery cycle life 20%+
