This product details our high-purity Low Sodium Boehmite (γ-AlOOH), a premium microcrystalline aluminum hydroxide powder with an Al₂O₃ content of 81%. Specially processed to achieve extremely low soda (Na₂O) levels, it is the ideal precursor for manufacturing high-performance alumina ceramics and advanced materials.
Key Applications & Uses
Advanced Ceramic Precursor: The primary material for synthesizing low-sodium alumina used in high-strength electronic ceramics, microcrystalline ceramics, and transparent ceramics.
Catalyst & Adsorbent: Used in the preparation of high-surface-area activated alumina for catalysts, desiccants, and adsorbents.
Advanced Abrasives & Coatings: A key starting material for producing submicron and nano-sized α-alumina powders with high conversion rates for precision abrasives and wear-resistant coatings.
High-Voltage Insulation: Essential for manufacturing advanced insulators and automotive/aerospace spark plugs that require exceptional electrical resistance and thermal stability.
Engineering Components: Serves as a raw material for heat-resistant, wear-resistant ceramic devices and as a high-performance filler in electrochemical systems.

Why Choose Our Low Sodium Boehmite?
Ultra-Low Sodium Content: Critically low Na₂O levels (as low as 0.003%) prevent glass phase formation during sintering, leading to ceramics with superior mechanical strength, enhanced electrical insulation, and higher thermal stability.
High Purity: Controlled impurity profiles (Si, Fe, Ca, Mg) ensure consistent performance and final product quality, batch after batch.
Controlled Particle Size: Available in a range of precisely defined particle size distributions (from submicron to coarse).
