Copper (II) oxide is a higher oxide of copper and belongs to the monoclinic crystal system. It occurs as a black solid with an ionic structure that melts above 1200°C with some loss of oxygen.
Gallium selenide is a chemical compound having a hexagonal layer structure similar to that of gallium sulfide. It readily reacts with acids. Gallium selenide crystals are widely being used in photoconductor and non-linear optical material.
Copper indium gallide selenide (CIGS) is an I-III-VI semiconductor material composed of selenium, gallium, indium and copper. It is a tetrahedrally bonded semiconductor largely found in chalcopyrite mineral.
Chromium bromide is a water soluble, highly crystalline inorganic compound with the formula CrBr3. It is used in catalysts to polymerize olefins. Ultra-high purity and ultra-high compositions have good optical quality and are very useful.
Gold is a chemical element with Au as its symbol. It belongs to group 11, periodic number 6 of the periodic table. Its atomic number is 79.
Bismuth iodide is an inorganic compound with the chemical formula BiI3. It occurs as gray-black solid and adopts a distinctive crystal structure having iodide centers at a hexagonally closest-packed lattice. It forms upon heating the mixture of bismuth and iodine powder.
Arsenic trisulfide is an inorganic compound with the chemical formula As2S3. It occurs in a bright yellow mineral named as orpiment and a red-orange mineral called as realgar.
Silicon carbide is a compound of silicon and carbon with the chemical formula SiC. It occurs in the extremely rare mineral moissanite. Silicon carbide grains are bonded together by sintering to form hard ceramics that are used in applications requiring high endurance.
