Product Introduction

Crystalline aluminum chloride is an inorganic compound with the chemical formula AlCl ₃ ·6H ₂ O, also known as crystalline aluminum trichloride or hexahydrate aluminum chloride, has a molecular weight of 241.43 and appears as orange or light yellow crystals. It is an orthorhombic crystal with a density of 2.398 g/cm ³ It is deliquescent, non-combustible, and easily soluble in water, anhydrous ethanol, ether, and glycerol. Its aqueous solution is acidic.

The technical index conforms to the Chinese Chemical Industry Standard HG/T3541-2011.

The production process of crystalline aluminum chloride varies depending on the raw materials. Some use metallic aluminum as a raw material, while others use bauxite. In China, bauxite is mainly used as the raw material for crystalline aluminum chloride.

Crystalline aluminum chloride is also a type of inorganic flocculant and can be used in the treatment of drinking water and industrial water. In precision casting, crystalline aluminum chloride can replace ammonium chloride as a shell hardener for investment casting, offering advantages such as stable quality, high shell strength, easy adjustment, improved working conditions, and good overall economic benefits.

Currently, most precision casting production in China uses water glass as a binder. Ammonium chloride, magnesium chloride, and aluminum chloride are commonly used as hardeners. However, during use, ammonium chloride releases ammonia gas, severely worsening working conditions. Magnesium chloride has high solution viscosity, affecting the hardening and drying speed. Moreover, its high impurity content easily causes defects such as shell delamination, peeling, and sand inclusion. Therefore, ammonium chloride and magnesium chloride are unsuitable as hardeners for investment casting, and manufacturers have successively adopted crystalline aluminum chloride to replace ammonium chloride and magnesium chloride as hardeners.
