Alumina ceramic discharge bushing

Alumina ceramic discharge bushings and irregularly shaped structural components, as core components in the field of electronic ceramics, have the following characteristics in terms of performance and application:

Ⅰ. Material Characteristics

1. Purity Grade: 99% alumina ceramic (Al₂O₃ content ≥99%) features high insulation, high temperature resistance (melting point 2054℃), and excellent wear resistance, making it suitable for high-frequency insulation and high-temperature corrosive environments. Its dielectric constant (9.9@1MHz) and dielectric loss (≤0.0002) are significantly superior to 96% alumina ceramic, making it suitable for precision electronics fields such as 5G communication.

2. Forming Process:

● Dry Pressing: Suitable for mass production of simple-shaped bushings, offering high efficiency and controllable costs.

● Isostatic Pressing: Used for complex irregularly shaped parts, resulting in uniform green body density and a bending strength of up to 700MPa after sintering.

● Injection Molding: Can manufacture structural components with micron-level precision, such as electronic connectors and sealed housings.

Ⅱ.Application Scenarios

1. Electronic Ceramic Structural Components: As integrated circuit substrates and high-frequency insulating materials, 99% alumina ceramics are widely used in semiconductor equipment, vacuum furnace tubes, and precision instruments due to their low dielectric loss and high thermal conductivity.

2. Wear-Resistant and Corrosion-Resistant Components: Discharge bushings utilize their high hardness (Mohs hardness 9) and impact resistance, making them suitable for material handling systems in chemical, metallurgical, and other industries.

3. Customized Shaped Parts: Non-standard ceramic tubes, bushings, and sealing rings can be produced through precision machining to meet the special needs of mechanical sealing, biomedical, and other fields.
