Description

Aluminium oxide ( Al 2 O 3 Al 2 O 3 ), also known as alumina, is a white, odourless, crystalline or amorphous substance composed of aluminium and oxygen atoms, with significant industrial and technological applications.​ Chemical and Physical Properties Chemical Formula: Al 2 O 3 Al 2 O 3 .​ Molar Mass: 101.96 g/mol.​ Density: ~3.95 to 4.1 g/cm³ (depends on crystal structure).​ Melting Point: ~2,072°C.​ Boiling Point: ~2,977°C.​ Appearance: White, odourless, solid; insoluble in water and most organic solvents.​ Structure: Most stable crystalline form is corundum, where oxygen ions form a hexagonal close-packed structure, and aluminium ions occupy two-thirds of octahedral sites.​ Polymorphism: Exists in several forms, with alpha (corundum) being the hardest and most stable; gamma alumina is porous and used in catalysis.​ Chemical Behaviour Amphoteric Nature: Reacts with acids (acts as a base) and with bases (acts as an acid), forming salts and water in both cases.​ Redox Properties: Typically features aluminium in the +3 oxidation state; participates in redox reactions, such as electrolytic reduction to produce metallic aluminium.​ Major Uses Abrasives: Due to its high hardness, alpha alumina is used as abrasive materials (sandpaper, grinding wheels).​ Refractories: Used for lining furnaces, kilns, and reactors due to its thermal stability.​ Ceramics and Electrical Insulators: Essential in producing advanced ceramics and as a dielectric material in electronics.​ Catalyst Supports: Gamma alumina, with a highly porous structure and large surface area, is widely used as a catalyst support in petrochemicals and chemical industry.​ Gemstones: The naturally occurring crystalline forms corundum, ruby, and sapphire are all varieties of alumina.

Ferrous borate extra pure is a high-quality iron(II) borate compound (commonly referred to as iron(II) borate or ferrous borate), used predominantly in laboratory and industrial settings for applications that demand high purity standards. It typically appears as a fine, air-sensitive solid and is valued for its chemical stability under controlled conditions. The compound features a high degree of purity, making it especially suitable for analytical work, advanced research, and select industrial processes.​ Product Description for Website Ferrous borate extra pure (Iron(II) borate) is a premium-grade inorganic salt prepared to strict purity standards, ensuring low levels of contaminants and accurate stoichiometry for scientific and technical applications. The product is carefully processed and packaged to maintain its chemical integrity and support reliable results in laboratory analysis and synthesis.​ Synonyms: Iron(II) borate, Ferrous borate Chemical Formula: Fe(BO2)2 (hydrated forms and other stoichiometries possible) Appearance: Pale solid, may be air-sensitive Grade: Extra pure (analytical/research grade) Applications: Used in specialized laboratory analyses, catalyst systems, advanced inorganic synthesis, and as a starting material in certain industrial applications where high purity is critical.​ Key Features High purity and controlled chemical analysis for reliable, reproducible results Packaged with minimal contamination risk and maximum shelf-life Suitable for use in chemical research, formulation, and manufacturing at the analytical level​ Safety & Handling Ferrous borate is generally stable under typical laboratory conditions but should be handled with care as it may be sensitive to atmospheric moisture and air. Use standard personal protective equipment and store in a tightly sealed container in a cool, dry environment.​ This concise description is suitable for use as a base product summary or catalog entry for e-commerce or laboratory supply websites, ensuring clarity for research and procurement professionals.​
