C.I. 77795 - Nature
Open Data Verified Data
gray sponge-like metal, pure. Melting point (1773.5±1) ° C; Boiling point of about 3827 ° C; Relative density 21. 447; Cloth hardness 55; Resistivity 10. 6Q.cm (20 ° C). Platinum has good wear resistance and the highest electrical conductivity, and its ductility and plasticity are close to that of Metallography. Aqueous solutions of bases and acids have no effect on platinum, and only aqua regia dissolves platinum in the hot and cold states. Molten alkali and cyanide can attack platinum.

| Introduction | Platinum carbon, also known as Platinum carbon, Platinum carbon catalyst, Pt/C. It belongs to the noble metal catalyst, the appearance is black powder, the molecular weight is 195.08, the molecular formula is Pt/C. Platinum-carbon catalyst is a kind of carrier catalyst that carries platinum on activated carbon, which is one of the most commonly used noble metal catalysts. Can be used in pharmaceutical, electronic and other fields, the application is more extensive. |
| Application | 1. Organic Synthesis: hydrogen removal reaction, aromatic ring hydrogenation reaction, hydrogen peroxide decomposition, gas purification; 2. Platinum carbon is used for the combination reaction of hydrogen and oxygen, and hydrogen is purified from oxygen, argon, nitrogen, carbon dioxide, air and helium; 3. Platinum carbon is used for the combination reaction of oxygen and carbon tetrachloride to purify oxygen from nitrogen; 4. Platinum carbon is used in the combination reaction of hydrocarbon compounds and oxygen, and the hydrocarbon compounds are purified from oxygen, nitrogen, carbon dioxide, air, helium and argon; 5. Platinum carbon is used for the combination reaction of carbon monoxide and oxygen, and carbon monoxide is purified from carbon dioxide, nitrogen and air. |
| Application | used in the manufacture of precision alloys used as catalysts, oxidants and gas absorbents for the production of nitric acid by the oxidation of ammonia for the manufacture of jewelry, wires, laboratory containers, thermocouples, corrosion-resistant equipment, dental materials, etc, platinum powder can be used as catalyst for electrical instrument, chemical industry and manufacturing precision alloy. used in the preparation of platinum salts, catalysts (platinum Black, Platinum asbestos) and chemical instruments, jewelry, etc. mainly used as conductive components of thick film paste in the electronics industry, microelectronic technology in the high stability, high reliability, excellent performance of conductive paste and electrode paste conductive composition. |
| production method | industrial production of platinum available platinum ore by dry manufacturing; Also can be copper, nickel sulfide ore preparation of copper, nickel produced in the production process of by-products as raw materials, produced by wet smelting. Wet extraction of nickel and copper have been extracted by adding the residual components of aqua regia extraction, filtration, adding ammonium chloride to the filtrate reaction to generate ammonium chloroplatinic acid precipitation, filtration, ammonium chloroplatinic acid heating decomposition, approximately 99.99% of the finished platinum product was obtained. Alternatively, the ammonium chloroplatinate solution is added to an electrolytic cell, and electrolysis is carried out at A cell voltage of about 1.5V and A current density of 2 to 3 A/cm3 to obtain about 99.98% of A finished platinum product. |
