GADOLINIUM (III) CHLORIDE - Introduction

Gadolinium chloride hydrate is an inorganic compound with the chemical formula GdCl3 · xH2O. It is a white or pale yellow crystal, soluble in water and alcohol, slightly soluble in ether and acetone. Gadolinium chloride hydrate exists in various hydrate forms, the most common of which are Hexahydrate (GdCl3 · 6H2O) and nonahydrate (GdCl3 · 9H2O).

Gadolinium chloride hydrate has important applications in medicine, chemistry and materials science. In medicine, it is used as a magnetic resonance imaging (MRI) contrast agent, which can improve the quality and resolution of MRI images. In chemical research, it is often used as a catalyst, a coordination reagent and a catalyst for redox reactions. In materials science, it is often used to prepare magnetic and optical materials.

There are two main methods for preparing Gadolinium chloride hydrate. One is to react Gadolinium chloride with water to form hydrate, and the other is to react Gadolinium chloride with anhydrous hydrochloric acid to form chlorocerium, and then to form Gadolinium chloride hydrate by adding water.

Regarding safety information, Gadolinium chloride hydrate has low toxicity under normal use conditions. However, as a chemical substance, it is still necessary to pay attention to its safe operation. Avoid contact with skin and eyes, avoid inhaling its dust or solution. Wear appropriate protective gloves and glasses during use. In case of accidental contact or ingestion, seek medical help immediately.
