99.8% alumina is highly pure and has been developed for semiconductors. It has excellent chemical and plasma resistance, and dielectric properties for high-voltage applications. It can be used for semiconductor applications including PVD, CVD, and CMP oxide etching, ion implantation, and photolithography. This percentage of alumina is widely used in the semiconductor industry.

1. Strong durability: Although lightweight and thin, alumina ceramics are a very durable material. Its hardness means that even after long-term use, it is not prone to mechanical damage and scratches, so frequent replacement is not necessary.

2. Excellent thermal and dielectric properties: Aluminum oxide has excellent thermal and dielectric properties in various applications. It has good heat resistance and impact resistance, and is an ideal insulation material that does not allow current to pass through.

3. The higher the purity, the more obvious the advantages: Purity is very important for alumina ceramics. High purity aluminum oxide materials have more outstanding quality. We offer various purity levels of alumina materials, with the most popular including 96%, 99.5%, and 99.8%.

99.8% alumina features: 99.8% alumina is also one of the commonly used high purity grades. Similar to a purity of 99.5%, this material provides greater resistance and strength in thin materials and is an ideal choice for precision applications.
