Indium(III) chloride tetrahydrate

Indium(III) Chloride tetrahydrate, ≥99.9% trace metals basis, is a white, hygroscopic crystalline solid which is highly soluble in water. It acts as a versatile Lewis acid and indium source for advanced materials. It has Orthorhombic crystal structure with octahedral In(III) coordination. It serves as a reliable indium source for doping materials and as a precursor to indium oxide (In₂O₃) in electronics, including semiconductors, touchscreens, and thin-film transistors.

Indium(III) Chloride tetrahydrate provides a clean indium source for synthesizing advanced indium compounds in different applications. It enables novel SrTiO₃@ZnIn₂S₄ and SrCrO₃@ZnIn₂S₄ heterojunctions with 1.09x and 1.54x higher hydrogen evolution rates than pure ZnIn₂S₄.These heterostructures excel in light harvesting, charge separation, and reduced resistance for efficient photocatalytic H₂ production. In addition, Indium(III) Chloride tetrahydrate enables synthesis of ZnIn₂S₄ (ZIS), a visible-light photocatalyst via microwave hydrothermal method. Combined with BiFeO₃ (BFO), it forms piezo-enhanced heterojunctions that harvest solar and mechanical energy for superior H₂ evolution.This binary photo-/piezoelectric system shows strong potential in renewable energy and environmental remediation.Furthermore, Indium(III) Chloride tetrahydrate enables synthesis of 2D CuInSe₂ (CIS) materials via CVD, delivering excellent optoelectronic properties and ordered copper vacancies.These qualities make CIS ideal for high-performance photovoltaics and photodetectors. It is also used to fabricate Indium tin oxide(ITO) thin films for various applications such as gas sensors, solar cells, and conductive inks.
