alphaAlOH3

alphaAlOH3 refers to a specific crystalline phase of aluminum hydroxide. Aluminum hydroxide, with the chemical formula Al(OH)3, is a naturally occurring compound that exists in several polymorphs, or different structural forms. The alpha phase, often designated as α-Al(OH)3, is one of the most common and stable forms.

This material is typically a white, amorphous solid in its pure form. It is insoluble in water but dissolves in strong acids and bases. alphaAlOH3 is found in nature as the mineral gibbsite. Gibbsite is a key component of bauxite ore, which is the primary source for aluminum metal production.

In industrial applications, alphaAlOH3 is widely used as a flame retardant. When heated, it undergoes an endothermic decomposition, releasing water vapor which cools the material and dilutes flammable gases. This property makes it valuable in plastics, rubber, and other polymeric materials. It also serves as a precursor for the production of alumina (Al2O3), which is used in ceramics, abrasives, and as a catalyst support. Furthermore, aluminum hydroxide, including the alpha phase, is employed in antacids and as a vaccine adjuvant. The specific properties and performance of alphaAlOH3 can be influenced by factors such as particle size, surface area, and purity.
