99.999% Ultra High Purity Alumina: Top Grade Nano Powder for Advanced High-Tech Manufacturing

Core Definition of 99.999% Ultra High Purity Alumina

The industry standard gives clear specification of this high-end nanomaterial at the very beginning: 99.999% Ultra High Purity Alumina refers to Al₂O₃ powder with purity ≥99.999%, total trace impurities controlled below 10ppm. In practice, Jinghuang Nano’s mass produced 99.999% grade alumina can even keep total impurities under 5ppm, far exceeding regular industrial standard.

Key Chemical Composition Requirements

From real case studies in semiconductor manufacturing, any single impurity above 1ppm such as iron, silicon or sodium will cause irreversible performance damage to sensitive electronic components. The 2026 data from Global High Purity Alumina Association confirms that 92% of high-end sapphire substrate producers require 99.999% grade alumina as core raw material.

Core Physical Property Indicators

Typical qualified 99.999% Ultra High Purity Alumina shows average particle size between 0.2μm and 5μm, specific surface area from 5 to 20 m²/g, melting point at 2072℃, and 9.0 Mohs hardness, which meets all strict high temperature and high strength application demands.

Step-by-Step Mass Production Process of 99.999% Ultra High Purity Alumina

Commercial stable 99.999% Ultra High Purity Alumina production follows 5 strictly controlled steps to eliminate trace impurities completely.

1. High purity aluminum source pre-treatment: remove primary iron, silicon, sodium impurities via 3-level distillation purification process
2. Hydrothermal crystallization: adjust pH value to 8.5-9.0 to form homogeneous aluminum hydroxide precursor without residual organic additives
3. High temperature calcination: keep constant 1600℃ calcination for 4 hours to remove all residual moisture and low-boiling-point components
4. Ion exchange deep purification: pass precursor through 4 groups of special resin columns to reduce heavy metal impurities to below 1ppm
5. Laser particle size classification: filter out oversized particles to achieve narrow, consistent particle size distribution for different application demands
