Nickel sulfide Chemical Properties,Usage,Production

Chemical Properties

yellowish; naturally occurring nickel mineral [KIR81] [CRC10]

Uses

Nickel subsulfide is used as a catalyst in refining crude oil containing a considerable amount of sulfur.

Uses

Nickel sulfide was implanted in mice, to induce the growth of malignant fibrous histiocytomas.

Production Methods

Nickel subsulfide can be prepared by a direct reaction between nickel and sulfur at a temperature over 300
C. This process makes it possible to prepare the purest preparation in the form of a brittle melt or monocrystals. The largest industrial source of nickel subsulfide is the metallurgic process of nickel matte smelting. Nickel matte consists of nickel subsulfide and some quantities of iron and copper sulfides. It is an intermediate product in nickel metallurgy regardless of the type of the processed ores.

General Description

Pale yellowish-bronze metallic-lustrous crystals or shiny gold-green (metallic) crystalline powder.

Air & Water Reactions

NICKEL SULFIDE -150 MESH 99.7% is sensitive to prolonged exposure to air. Insoluble in water.

Reactivity Profile

Inorganic sulfides, such as NICKEL SULFIDE -150 MESH 99.7%, are generally basic and therefore incompatible with acids. Many of these compounds are reducing agents and therefore react vigorously with oxidizing agents, including inorganic oxoacids, organic peroxides and epoxides. Simple salts of sulfides (such as sodium, potassium, and ammonium sulfide) react vigorously with acids to release hydrogen sulfide gas.

Fire Hazard

Flash point data for NICKEL SULFIDE -150 MESH 99.7% are not available. NICKEL SULFIDE -150 MESH 99.7% is probably combustible.

Flammability and Explosibility

Non flammable

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, tumorigenic, and teratogenic data. Poison by intraperitoneal and intratracheal routes. An experimental teratogen. Other experimental reproductive effects. Human mutation data reported. When heated to decomposition it emits toxic fumes of SOx. See also NICKEL COhlPOUNDS and SULFIDES.
