Kyanite, a high-alumina silicate mineral with excellent electrical insulating properties, finds applications in electrical components for various purposes, primarily as an insulating material and as a substrate for electronic devices.

One of the primary uses of kyanite in electrical components is as an insulating material in high-temperature and high-voltage applications. Kyanite's unique crystal structure and mineral composition make it an excellent electrical insulator, capable of withstanding extreme temperatures and electrical stresses without breakdown or degradation. Kyanite insulators are used in electrical transformers, circuit breakers, insulators, and other power distribution equipment to provide reliable insulation and safety in electrical systems.

Moreover, kyanite serves as a substrate material for electronic devices, such as semiconductor chips, integrated circuits, and electronic packaging. Kyanite substrates offer excellent thermal conductivity, mechanical strength, and dimensional stability, making them suitable for use in high-power and high-frequency electronic applications. Kyanite-based substrates provide reliable support and thermal management for electronic components, ensuring optimal performance and reliability in demanding operating conditions.

Additionally, kyanite can be used as a filler and reinforcement material in electrical insulation composites and laminates. Kyanite-filled composites and laminates exhibit enhanced mechanical strength, thermal stability, and dielectric properties, making them suitable for use in electrical insulation systems, such as motor windings, coil forms, and insulating barriers. Kyanite-filled materials provide improved performance and durability in electrical applications, reducing the risk of electrical failures and downtime.
