Description

Application

Anhydrous chromium chloride is an important precursor for the low temperature synthesis of anhydrous metal sulfides, nitrides, phosphides, etc. It is also an important precursor for the synthesis of chromium containing mixed metal complexes; example lithium chromium chloride (Li₂CrCl₄), which shows rapid lithium ion conduction.

Anhydrous chromium chloride finds applications as catalysts, chromizing ferrous metals, steel, etc. The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.

Chromium chloride powder is air and water sensitive. Beads have lower surface area and pour easily.

The vapor-phase co-reductions with other metal halides by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties.

Formation of metal-anion arrays within layered perovskite hosts. Preparation of a series of new metastable transition-metal oxyhalides, (MCl)LaNb(2)O(7) (M = Cr, Mn, Fe, Co).

Liliana Viciu et al.

Inorganic chemistry, 41(13), 3385-3388 (2002-06-25)

A new series of transition-metal oxyhalides (MCl)LaNb(2)O(7) (M = Cr, Mn, Fe, Co) have been prepared by a simple topochemical route. Layered perovskite hosts (ALaNb(2)O(7), A = Li, Na, K or Rb) were reacted with the corresponding anhydrous metal halides

Effects of short-term chromium supplementation on insulin sensitivity and body composition in overweight children: randomized, double-blind, placebo-controlled study.

Chan-Won Kim et al.

The Journal of nutritional biochemistry, 22(11), 1030-1034 (2011-01-11)

Excessive body weight is inversely associated with insulin sensitivity in children and adults. Chromium supplementation produces modest improvement in insulin sensitivity in adults. The aim of this study was to examine the beneficial effects of chromium supplementation on insulin sensitivity
