Deqing Yehui Ceramic Parts Manufacture Co., Ltd specialize in manufacturing alumina ceramics products
Alumina ceramics are widely used in electronic products due to their high insulation, high-temperature resistance, and excellent thermal conductivity. Below are typical application cases and market performance:
1. **Semiconductor Manufacturing Equipment**
Alumina ceramic components (purity ≥99.5%) are utilized in etching, deposition, and other processes to create plasma-corrosion-resistant chamber liners, electrostatic chucks, and wafer stages. For example, Kyocera Corporation (Japan) employs alumina ceramic focus rings and protective rings to precisely control plasma distribution, improving chip yield. Suzhou Xinhe Semiconductor has developed high-precision alumina ceramic components using novel preparation processes, which have been integrated into domestic semiconductor equipment, accelerating the localization of critical components.
2. **Electronic Substrates and Packaging**
Alumina ceramic substrates (e.g., 96% alumina type), with their high thermal conductivity (17–25 W/m·K) and low dielectric loss (<0.0002 @1MHz), are extensively used in LED substrates, high-voltage insulators, and 5G communication modules. For instance, Kyocera’s alumina ceramic circuit boards enhance heat dissipation in automotive high-power LED lamps, extending lifespan by 30%. In 2022, the global alumina ceramic substrate market reached $3.2 billion and is projected to grow to $5.1 billion by 2030, with a compound annual growth rate (CAGR) of 7.5%.
3. **Sensors and Power Devices**
In new energy vehicles, alumina ceramics are applied in high-temperature sensors and power electronics packaging. Tesla’s Model 3 inverter employs an alumina/SiC composite heat dissipation substrate with a thermal conductivity of 42 W/(m·K), ensuring stability under high-power operation. Additionally, Yangzhou Zhongtianli’s γ-Al₂O₃ fillers boost the thermal conductivity of 5G base station chip packaging materials to 5.6 W/(m·K).
These cases highlight the irreplaceable role of alumina ceramics in high-end electronics, driving continuous market expansion, particularly in semiconductor and new energy sectors where demand remains robust.
