Cobaltous chloride, chemical formula CoCl2. It is pink to red crystal and anhydrous is blue. It is slightly deliquescent and soluble in water, ethanol, ether, acetone and glycerol. Used for analysis reagent, humidity and moisture indicator, ammonia absorbent.
Cobalt chloride is prepared by the inte…
Cobalt carbonate is a red monoclinic crystalline or powder. Toxic, irritating eyes, respiratory system and skin.It is mainly used to produce cobalt chloride, cobalt sulfate, cobalt oxide, cobalt metal and cobalt naphthenate.It is also used for making discolored pigments, glass pigments, ceramics, fe…
Since 1999 et al, Ordered mesoporous carbon materials were synthesized by template MCM-48 for the first time. Ordered mesoporous carbon materials with different structures and morphologies were synthesized successively, such as:Single crystal, spherical, rod, fibrous, thin film, etc.Because of the…
The cadmium oxide is Green-yellow, reddish-brown or blue-black crystals or powders, insoluble in water, soluble in dilute acids and ammonium salts. Cadmium oxide can be used as analytical reagent and catalyst, as well as in the preparation of high purity cadmium salt, cadmium plating solution and ce…
Niobium pentoxide is a white powder. is a typical n-type transition metal oxide semiconductor with a band gap of 3.4-5.3 e V, a melting point of 1485 (+5 C) and a relative density of 4.47 g/cm. Niobium pentoxide has high chemical stability. It is insoluble in water and acid (except sulfuric acid and…
Arsenic-copper alloys are mainly used as additives for copper alloys. When a small amount of arsenic (0.15-0.5%) is added into copper, the mechanical properties of the same alloy change little, but the thermal conductivity and electrical conductivity of copper are significantly reduced, and the proc…
In the preparation of zirconium hydride powder, it is easy to be affected by the following factors which affect the quality of zirconium hydride powder.In the process of preparing zirconium hydride powder, the formation of product quality is affected by all the technicians and operators involved in…
Metal cobalt powder: The appearance is gray, and the particle shape is spherical or irregular, which depends on the smelting process. It is mainly used in powder metallurgy, thermal spraying and so on.The binder of cobalt powder in metallurgy can ensure that the cemented carbide has certain toughnes…
Pure metal iron is silver white, iron powder is black, this is an optical problem, because the surface area of iron powder is small, there is no fixed geometric shape, and the crystal structure of iron block is geometric shape, so iron block absorbs part of the visible light, reflecting the other pa…
Tourmaline is also called Tomalin. Tomalin was first discovered in Sri Lanka. People noticed that this gemstone carries electric charge when heated. This phenomenon is called pyroelectric effect, so it is named tourmaline.Tourmaline is a multi-element natural mineral， mainly consists of more than 10…
