Tungsten hexachloride, or tungsten (VI) chloride, is a blue-black or blue violet crystalline solid at room temperature, with CAS No. of 13283-01-7, molecular formula of WCl6, relative density of 3.52 (25°C), and purity of up to 99%~99.99 %. At lower temperatures, WCl6 becomes wine-red in color. A red form of the compound can be made by rapidly condensing its vapor, which reverts to the blue-black form on gentle heating. Properties 1. Soluble in carbon disulfide, ether, ethanol, benzene, phosphorus oxychloride…

Tungsten pentachloride is a hygroscopic black crystal with molecular formula of WCl5 (or W2Cl10), CAS No. of 13470-14-9, and relative density of 3.88g/cm3. WCl5 is an inorganic compound, which is analogous in many ways to the more familiar molybdenum pentachloride. Properties 1. Dissolved in water and decomposed to form W2O5. 2. Easily decomposed if exposed to the air. 3. Heated in the air to obtain tungsten oxytetrachloride (WOCl4). 4. Very sensitive to humidity, placed in the air to generate a…

Tungsten tetrachloride, or tungsten (IV) chloride, is a diamagnetic black solid with the molecular formula of WCl4, CAS number of 13470-13-8, and a density of 4.62g/cm3. The hygroscopicity of WCl4 is less strong than WCl5, but it’s easy to hydrolyze. WCl4 does not melt or sublimate even if heated, but it resolves at melting point or hydrolyzes in a vacuum. WCl4 is an inorganic compound with corrosivity. The compound is of interest in research as one of a handful of…

Tungsten dichloride dioxide is a thin yellow-colored crystalline with the chemical formula of WO2Cl2, and CAS No. of 13520-76-8. It is used as a precursor to other tungsten compounds. Physical Properties 1. Stable at normal temperature and pressure. 2. Dissolvable in cold water, decomposed in hot water, soluble in ammonia and alkali, and insoluble in ethanol. 3. Like other tungsten halides, sensitive to moisture in the atmosphere, so the reaction tube must be opened in a dry nitrogen atmosphere and…

Tungsten dichloride is a pale-gray amorphous powder with chemical formula of WCl2, molecular weight of 254.76, CAS No. of 13470-12-7, and density of 5.436g/cm3. WCl2 is easy to form a regular octahedron group. And it is mainly applied in the field of new materials as raw material. Properties 1. Very unstable in the air, and easily oxidized. 2. Dissolved in hydrochloric acid (HCL), ethanol (C₂H₅OH) and ether (C4H10O). 3. Saved in excess hydrogen chloride. 4. Decomposed at the temperature of…

Tungsten pentaboride, also called tungsten boride (W2B5), is a black powder with chemical formula of B5W2, molecular weight of 428.79100, exact weight of 430.00300, CAS No. of 12007-98-6, melting point of 210~214°C and boiling point of 110°C (1 Torr). It is somewhat toxic. Preparation Method In a vacuum or argon atmosphere, sintered at the temperature range of 1200~1300°C with 2mol tungsten powder and 5mol boron powder. Applications 1. For fine chemicals. 2. As a pharmaceutical intermediate or materials intermediate. Toxicity…
