Anhydrous gallium chloride is a high-purity inorganic compound with the chemical formula GaCl₃. It exists as white needle-like crystals or powder under normal conditions. As a strong Lewis acid, it exhibits highly reactive chemical properties. This product is highly hygroscopic, rapidly absorbing moisture from humid air and undergoing “fuming” hydrolysis. As a critical gallium source precursor, it serves as an indispensable high-end raw material in the semiconductor industry, organic synthesis, and specialty material preparation.
We offer high-purity gallium trichloride powder in various specifications, supported by professional moisture-proof custom packaging. Contact us for samples.

New Energy & Electrochemistry: Used in formulating ionic liquid plating solutions for metal electrodeposition under specialized conditions.
Advanced Materials Fabrication: Serves as a precursor for synthesizing copper gallium selenide thin-film solar cell materials and other functional compounds.
Q1: Why must this product be handled in an anhydrous environment?
A1: This substance is highly hygroscopic. It undergoes violent hydrolysis upon contact with water, emits fumes, and becomes ineffective. All operations must be conducted under strictly dry, inert atmospheres.
Q2: What are its primary applications?
A2: Two core uses: as a gallium precursor in semiconductor MOCVD processes and as a strong Lewis acid catalyst in organic synthesis.
Q3: What are the safety risks?
A3: Highly corrosive, posing severe burn risks to skin and respiratory tract. Full protective gear is required during handling, and refer to the MSDS.
Q4: What are the special packaging requirements?
A4: Must use vacuum-sealed, multi-layered moisture-proof packaging with inert gas (e.g., aluminum foil bags) to prevent degradation during transport and storage.
