Aluminium oxide hydroxide, also known by its chemical formula AlO(OH), is a compound that consists of the elements aluminium, oxygen, and hydrogen. It is a white, crystalline solid with the appearance of powder or granules. Aluminium oxide hydroxide is commonly found in nature as the mineral gibbsite.
The compound is formed through the combination of aluminium oxide (Al2O3) and water (H2O). It has a molar mass of approximately 78 grams per mole and a density of 3.1 grams per cubic centimeter. Aluminium oxide hydroxide is not soluble in water, and its solubility in acids is limited.
This compound is widely used in various industries, primarily as a precursor for the production of aluminium metal. It is also employed in the manufacturing of ceramics, catalysts, and as an additive in the production of glass. Aluminium oxide hydroxide has excellent adsorption properties, making it useful in wastewater treatment and purification processes. Furthermore, it serves as a component in antiperspirants, providing a barrier against perspiration by blocking sweat ducts.
In the field of medicine, aluminium oxide hydroxide is used as an antacid due to its ability to neutralize excess stomach acid. It can alleviate symptoms associated with conditions like indigestion, heartburn, and gastroesophageal reflux disease. Additionally, this compound is employed in the formulation of various skincare products, providing exfoliation and smoothing properties.
Overall, aluminium oxide hydroxide is a versatile compound with applications in numerous industries and consumer products, thanks to its varied chemical properties and beneficial characteristics.
