Cobalt Oxide Cas 1307-96-6, AAA

$25 - $40 / Kilogram (FOB)
MOQ: 1  Kilograms
Sample Available
 
escription:
This is obtained as an olive-green powder by heating the metal in air or steam or by thermal decomposition of the hydroxide, carbonate or nitrate. It has the sodium chloride lattice and is antiferromagnetic below 292�°K. When heated in oxygen above 400�° the black oxide Co3O4 is obtained. This oxide is isomorphous with magnetite Fe3O4, and has tetrahedrally surrounded cobalt(II) ions and octahedrally surrounded cobalt(III) ions. Both these oxides are readily reduced to the metal by heating in hydrogen or with carbon. The reactions of CoO with silica, alumina and zinc oxide are used to form pigments in the ceramic industry.

Application:
Mainly used for glass, enamel, ceramic, magnetic materials such as dense agent, azure blue, cobalt blue, cobalt green color colorant, catalyst, livestock nutrition agent. It is also used in the preparation of cobalt salts.
In pigments for ceramics; glass coloring and decolorization; oxidation catalyst for drying oils, fast-drying paints and varnishes; preparation of cobalt-metal catalysts, Co powder for binder in sintered tungsten carbide; in semiconductors.

Product Description:
Giemsa Stain is a laboratory reagent and stain for microscopy. A compound of eosin with methylene blue and its oxidation products. When blood films are stained using Giemsa stain, the nucleus and cytoplasm of white blood cells take on a characteristic blue or pink coloration. Giemsa stain functions by rearranging chromatin and inducing G bands producing a high quality stain for chromatin and the nuclear membrane. Giemsa stain is used to differentiate nuclear and/or cytoplasmic morphology of platelets, RBCs, WBCs, and parasites (1,2). The most dependable stain for blood parasites, particularly in thick films, is Giemsa stain containing azure B. Liquid stock is available commercially. The stain must be diluted for use with water buffered to pH 6.8 or 7.0 to 7.2, depending on the specific technique used.
