α-phase nano-alumina (α-Al₂O₃)

Features:

High hardness and wear resistance:

α-phase is the most stable crystal form of alumina, with a close-packed hexagonal structure and high hardness (Mohs hardness 9), which can significantly improve the wear resistance and scratch resistance of the coating.

High temperature resistance:

It can remain stable at high temperatures and is suitable for coating applications in high temperature environments (such as refractory materials, high-pressure sodium lamp coatings, etc.).

Insulation:

It has high resistivity and is often used in insulating coatings for electronic devices or protective layers for integrated circuit substrates.

Low specific surface area:

It usually has a small specific surface area, low activity, but good dispersibility, and is suitable for compounding with resins or plastics.

Applicable scenarios:

Wear-resistant coatings: such as mechanical parts and tool surface coatings.

High temperature protective coatings: such as aerospace components and furnace tube coatings.

Electronic packaging coatings: scenarios that require high insulation and dimensional stability.
