99% Alumina Oxide AL2O3 Ceramic Insulator Ball for High-voltage Power System
Product description
Ceramic insulators, due to their superior combination of electrical, thermal, mechanical, and chemical properties, have become core components for connecting, insulating, and protecting critical parts, especially suitable for cutting-edge technology and industrial fields where multiple extreme conditions (such as high voltage, high vacuum, high temperature, and strong corrosion) coexist. Their function is to ensure the stable, reliable, and safe operation of equipment in extreme environments.

| 3. Semiconductor manufacturing equipment | The wafer holder arm, radio frequency electrode, and gas distribution disk in a plasma etching machine and CVD equipment. | It is resistant to plasma corrosion, high temperature, and high cleanliness requirements, and does not contaminate the process. |
| 4. Energy and Lasers | Membranes and seals for sodium-sulfur batteries and fuel cells; discharge cavities and mirror supports for high-power lasers. | It is resistant to molten metal corrosion, high-temperature ion conductivity, or high-energy laser irradiation. |
| 5. Industrial Electronics and Sensors | Spark plug insulators, high-temperature sensor housings, thick-film circuit boards, and IGBT module boards. | It integrates electrical insulation, thermal conductivity, thermal shock resistance, and high-frequency stability. |
| 6. High-temperature and wear-resistant industrial environments (e.g., high-temperature kilns, wear-resistant liners, measuring probes) | As a thermocouple protection tube, furnace lining, wear-resistant guide wheel, and high-temperature observation window, it provides physical protection, thermal insulation, and wear resistance. | High hardness, high wear resistance, high temperature chemical stability, thermal shock resistance, and high melting point. |
| 7. Specialized connections and seals (e.g., vacuum/high-pressure through-wall connectors) | As a metallized insulator, it is brazed with metal electrodes to achieve hermetically sealed and electrically insulated power or signals from the atmospheric side to the vacuum/high-voltage side. | It can be metallized, has high airtightness, high insulation, high mechanical strength, and a coefficient of thermal expansion that matches that of metals. |
