Classification by Performance:
(1) High-Purity Yttrium Oxide Ceramics
In the field of electronic engineering, the purity requirements for materials are extremely high. High-purity yttrium oxide ceramics (e.g., content greater than or equal to 99.99%) ensure the stable performance of electronic component manufacturing equipment. Taking high-purity yttrium oxide ceramic discs as an example, their excellent corrosion resistance, plasma resistance, and high-temperature resistance ensure stable operation of equipment for extended periods in high-temperature and harsh environments, reducing equipment failures and downtime caused by material issues, extending component lifespan, and lowering maintenance and replacement frequency. This is a crucial support for ensuring stable manufacturing equipment performance, guaranteeing product quality, and improving production efficiency.
(2) Electrically Insulating Yttrium Oxide Ceramics
For components used in high-voltage and high-current reaction chambers, electrical insulation is an important evaluation indicator. Yttrium oxide coatings, due to their superior electrical insulation properties compared to alumina coatings, are an ideal choice for ensuring stable equipment manufacturing. Taking the top electrode coated with yttrium oxide as an example, it employs anodizing to spray high-purity yttrium oxide powder onto the substrate surface, forming a uniform and smooth coating with high electrical insulation strength, low dielectric constant, and high resistivity. This effectively prevents current leakage, reduces signal interference, and ensures stable operation of electronic equipment under extreme conditions. Therefore, it is widely used in the manufacturing and packaging of electronic components to fix the position of electronic components, prevent short circuits or overloads, and ensure the normal operation of circuits.
According to application classification:
(1) Yttrium oxide ceramics for module components
Yttrium oxide for module components is mainly used in electronic component manufacturing equipment. Taking yttrium oxide ceramic rings as an example, in plasma processing devices, yttrium oxide rings serve as insulating substrates, effectively reducing arc discharge between the device and the grounding part. Compared to quartz rings, yttrium oxide rings, due to their lower reactivity and higher dielectric constant, are less likely to react with materials, allowing for better transmission of electromagnetic waves and providing more uniform substrate conditions for the production of electronic components.
(2) Yttrium Oxide Coating
Yttrium oxide coating is applied to the surface of an object by spraying or coating to form a high-performance protective material, particularly suitable for equipment that needs to withstand extreme physical and chemical effects. It possesses excellent high-temperature resistance, wear resistance, and corrosion resistance, maintaining stable performance in high-temperature, high-pressure, and highly corrosive environments, significantly improving the durability and reliability of equipment, effectively reducing particulate contamination generated during electronic component production, and improving equipment efficiency and production precision.
