NIOBIUM SELENIDE Usage And Synthesis
Chemical PropertiesGray-black solid. Has higher electrical conductivity than graphite.
UsesIt is used as a potential substance for thin film solar cells as back contact material. It is widely used in electricity brush & special bearings because of its conductivity and lubricity property.
UsesThe two dimensional layered inorganic nanomaterials have drawn significant attention recently owing to their thickness dependent on physical and chemical properties. They find applications in photocatalysis, photovoltaics, 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.
UsesLubricant and conductor at high temperatures and high vacuum.
