Rhodium trichloride, also known as rhodium chloride, is a kind of red-brown powder, easy to deliquescence. Used in electronics, instrumentation, metallurgy and other industries, also used in electroplating operations, catalyst preparation.Rhodium trichloride trihydrate is a kind of Lewis acid, which can form various complexes with ligands.
Fe-Si-Al alloy is an alloy powder of 85% Fe, 9% Si and 6% Al, which is processed by special process and pressed into ring or E-type magnetic powder cores. It is commonly called Kool M_ u magnetic powder cores or Sendust powder in the market.
Nanometer iron oxide is a multifunctional material. When the size of iron oxide particles is small to nanometer scale (1-100 nm), the number of surface atoms, specific surface area and surface energy of iron oxide particles increase sharply with the decrease of particle size, which shows the characteristics of small size effect, quantum size effect, surface effect and macroscopic quantum tunnel effect.
Beryllium sulfate is a kind of white powder or cubic crystalline crystals, soluble in water, insoluble in organic solvents, highly toxic, and highly carcinogenic substance. It can cause dermatitis, ulcer and skin granuloma after absorption by human body. Industrial applications include beryllium salts, ceramics and chemical reagents.
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.
