The copper-holmium alloy has light red metallic luster and massive ingot shape. The content ratio is holmium (H0): 10% or 15%, and the remaining amount is mainly copper.
Cobalt hydroxide chemical formula Co(OH)2. It is a rose-red monoclinic or tetragonal crystal, insoluble in water, slightly amphoteric, insoluble in strong alkali, but soluble in acid and ammonium salt solution. The melting point is 1100-1200 C , which is amphoteric hydroxide.
Cobalt hydroxide has the following production methods:
Cobalt acetate is a purple-red deliquescent crystal with a slight acetic acid odor. It is heated to 140 C to form anhydrous substance. It is soluble in water, ethanol, dilute acid and amyl acetate. Its relative density is 1.705 and refractive index is 1.542. It has the possibility of carcinogenesis.
Cobalt sulfate, rose-red crystal. It is red powder after dehydration, soluble in water and methanol, slightly soluble in ethanol. It is also used in ceramic glaze and paint drier, electroplating, alkaline batteries, cobalt-containing pigments and other cobalt products. It is also used in catalysts, analytical reagents, feed additives, tire adhesives, lithopone additives, etc.
And cobalt sulfate is a dangerous explosive: it is non-flammable, toxic and irritating. The substance and its containers shall be disposed of as hazardous waste.
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 carbonate is a red monoclinic crystalline or powder.
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.
Ruthenium trichloride is a chemical and its molecular formula is RuCl3. It is a glossy crystal particle, usually grayish brown or dark red, corrosive, easily deliquescent, soluble in water, alcohol, acetone and ethyl acetate, and decomposed in hot water.
Chemical formula CdO for cadmium oxide. Green-yellow, reddish-brown or blue-black crystals or powders, insoluble in water, soluble in dilute acids and ammonium salts. Used for silver solder, glass making, electrodes, anti-nematode agents, organic reaction catalysts, ceramic glaze and cadmium plating. CdO smoke is produced when cadmium or its compounds are processed at high temperature.
