Product Overview

Aluminium Fine Powder 98% Extra Pure (CAS No. 7429-90-5) is a finely divided form of elemental aluminium intended for laboratory and materials-related applications. Aluminium is an electropositive metal capable of functioning as a reducing material in suitable chemical systems, while its powdered form facilitates close contact and uniform distribution within heterogeneous reaction mixtures and material formulations. These characteristics make aluminium powder useful in investigations involving metallic reactivity, reduction processes, and the preparation of aluminium-containing materials.

The Extra Pure grade is intended for routine laboratory work, research, preparative chemistry, and materials-science investigations requiring dependable metallic purity. It is suitable for experimental procedures in which aluminium is employed as a reagent, reducing material, elemental component, or metal-powder feedstock. The suitability of the fine powder for a particular materials-processing technique should be assessed according to its specified particle characteristics and the requirements of the intended procedure.

Typical Applications

• Reducing material in selected inorganic and wet-chemical synthesis procedures
• Laboratory investigation of oxidation–reduction and metal-displacement reactions
• Preparation of selected metals, alloys, and aluminium-containing intermediates
• Powder-metallurgy, compaction, and sintering research
• Development of aluminium-containing composite and intermetallic materials
• Preparation of experimental metal-powder blends and precursor mixtures
• Studies of aluminium surface reactivity, oxidation, corrosion, and passivation
• Academic, research, and industrial work in inorganic chemistry and materials science

Metallic aluminium has an established role as a reducing material in wet-chemical synthesis, while aluminium powders are also employed in powder-metallurgy and advanced-materials research.
