| | TUNGSTEN SELENIDE Usage And Synthesis |
| Chemical Properties | -325 mesh black powder(s); dry, solid lubricant with exceptional stability at high temperatures, and in high vacuum; used in the form of 99.8% pure material as a sputtering target to produce lubricant films [HAW93] [CER91] [AES93] | | Uses | Tungsten(IV) selenide is used as an important compound in electrochemical solar cells. It acts as a stable semiconductor. | | Uses | The two dimensional layered inorganic nanomaterials have drawn significant attention recently owing to their thickness dependent physical and chemical properties. They find applications in photocatalysis, phtotovoltaics, gas sensing, lithium ion batteries, field effect transistors, spintronics etc. Transition metal dischalcogenides represent an important class of inorganic 2D materials having the aforementioned applications. | | Uses | Owing to the thickness dependent physical and chemical properties, the two dimensional layered inorganic nanomaterials have drawn significant attention recently. They find applications in photocatalysis, phtotovoltaics, gas sensing, lithium ion batteries, field effect transistors, spintronics etc. Transition metal dichalcogenides represent an important class of inorganic 2D materials having aforementioned applications. The CVD grown monolayer films of MoS2, MoSe2, WS2 and WSe2 on insulating substrates such as SiO2 and sapphire are well suited for electronic and photovoltaic devices. | | Definition | Lamellarstructured,
dry, solid lubricant with exceptionally
high temperature and high vacuum stability.
Retains its lubricity to temperatures as low as
?265C. | | Hazard | TLV: 5 mg(W)/m3. |
