Common types

We offers the following product introduce：
Laminate White Fused Alumina
Laminate white fused alumina is a high-purity Aluminum Oxide material that has undergone special surface treatment, specifically designed for impregnating paper in laminate flooring products. It significantly improves the wear resistance, scratch resistance, and stability of impregnated paper by optimizing particle morphology and surface activity, while ensuring good compatibility with resin.

White Fused Alumina Micro Powder
White fused alumina Micro powder is a synthetic high-purity alumina solid powder, usually through fine grinding or chemical processes. Hardness is second only to diamond, suitable for aerospace engine coating and special wear-resistant parts. It can conduct heat quickly and block current, which solves the key contradiction between heat dissipation and high voltage insulation of electronic equipment.

Product features

Laminate White Fused Alumina
High hardness: The material is high-purity alumina material as 99.5%+, which has been calcined in a fixed furnace and achieved hardness Mohs 9+. Adding it can endow the floor with strong wear resistance, significantly extending its service life
Modified treatment, strong adhesion: After special process modification, the bonding strength with the resin is greatly enhanced, avoiding coating peeling.
Excellent dispersibility and high transparency: High dispersibility can greatly reduce agglomeration during use, making the impregnated paper uniform in color. The modified product has high transparency, especially suitable for light colored floor pattern design.

White Fused Alumina Micro Powder
High hardness: The high hardness gives the material a strong resistance to scratching, cutting and mechanical wear.
Strong thermal conductivity: WFA fine powder can conduct heat quickly to avoid local overheating, which is the core advantage of electronic heat dissipation materials and safety coating for lithium batteries.Integrated heat dissipation can be achieved to reduce the dependence on metal heat sink.
Excellent insulation: The isolated current can also conduct heat, perfectly suitable for high voltage insulation ceramic and chip substrate.

Application

Wear-resistant coating/ceramic

White fused alumina Micro powder can be used in mechanical seals, valves, mining machinery and other wear-resistant parts surface, can greatly extend the service life.

Space thermal management

Integrated into the thermal protection system to block the damage of extreme aerodynamic heat flow to the aircraft structure.

Tail gas catalytic carrier field

WFA fine powder can provide a substrate with high specific surface area to optimize the dispersion and reaction efficiency of the active components of the catalyst.

Precision surface polishing

It is used for semiconductor wafer planarization to achieve atomic level surface integrity.

Battery safety protection

A physical barrier is built on the surface of the diaphragm to inhibit the spread of thermal runaway inside the battery.

Package & Storage

Package: 25kg bag, 1000kg bag, customized package
Storage: Keep the bag sealed. Avoid direct sunlight.

FAQ

Q: What is the difference between Laminate white fused alumina and ordinary one ?

A: Laminate products undergo surface coating treatment, resulting in better dispersion and adhesion. Ordinary type is prone to settling and affects resin curing.

Q: Advantages in biomedical medicine?

A: Biological inertness avoids rejection reaction, the wear rate of ceramic joint is only 1/100 of metal, and the service life is more than 20 years.

Q: What are the advantages in the application of steel furnace?

A: Made into furnace wall lining, resist the long-term erosion of molten steel, and extend the life of the furnace by more than three times.

Q: Is there any application in the medical field?

A: Yes. White fused alumina Micro powder can be used to make artificial joints, dental materials, etc., with good biocompatibility, high hardness, strong wear resistance and other characteristics.

Q: How is alumina powder used in the refractory industry?

A: WFA fine powder can be used as aggregate or additive of refractory materials to improve the refractory degree, high temperature strength and erosion resistance of refractory materials. It is used in the lining of high temperature industrial kilns.
