| | Nickel sulfide Usage And Synthesis |
| 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 300C.
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. |
