White corundum is widely used in electronic industry, mainly due to its high purity, high hardness, excellent insulation and thermal stability. The following are the specific applications of white corundum in the electronic industry:

I. Grinding and polishing

White corundum abrasive is widely used in precision cutting, grinding, polishing and cleaning of electronic components. For example, semiconductor devices, integrated circuit boards, electronic ceramic components, etc. all need high-precision surface treatment. White corundum can ensure that the surface smoothness, flatness and geometric shape of these components meet higher requirements, thus improving the performance and reliability of electronic components.

II. Electronic ceramic materials

White corundum is an important raw material for manufacturing electronic ceramics, which is used to produce ceramic substrates, ceramic insulators and multilayer ceramic capacitors (MLCC). These materials have high dielectric constant, low dielectric loss and excellent insulation performance, and are suitable for high power and high frequency applications.

III. Packaging materials

White corundum can be used for packaging electronic components, providing mechanical protection and electrical insulation, while helping to dissipate heat. For example, white corundum-based ceramic packaging materials can withstand high temperatures and maintain good insulation performance.

IV. Piezoelectric ceramics

White corundum can be used to manufacture piezoelectric ceramics, which are applied to sensors, transducers and actuators. These piezoelectric ceramic elements have excellent piezoelectric properties and stability.

V. Microwave dielectric ceramics

White corundum can be used to make microwave dielectric ceramics, which are applied to microwave devices such as filters, resonators and antennas. These materials have low dielectric loss and high stability.

VI. Transparent ceramics

White corundum can be used to make transparent ceramics, which can be used in laser, infrared window and transparent nail-mounting. These transparent ceramics have high transparency and mechanical strength.

VII. Insulation coating

White corundum can be used to prepare insulating coatings for electronic components, which can prevent electrical short circuit and improve the reliability of components.

VIII. Thermal management materials

The high thermal conductivity of white corundum makes it an important heat dissipation material in electronic devices, which can be used to manufacture electronic components such as radiators, packaging substrates and semiconductor ceramics.

IX. Preparation of ultrapure water

White corundum can be used for manufacturing microporous ceramic filters and terminal filtration in the preparation of ultra-pure water in electronic industry.

X. Thermal insulation and sintered insulating materials for electronic components

White corundum micropowder can be used for thermal insulation and sintering isolation of electronic ceramics to ensure the stability of components during high temperature sintering.

White corundum is widely used in electronic industry, and its high performance makes it an indispensable material in modern electronic manufacturing.
