| 应用领域 | Uses: Platinum、gold、and nickel ores contain palladium. Palladium has been used as a hydrogenation catalyst. [HSDB] One of 6 metals in the platinum group that also includes Rh、Ru、Ir、and Os、Highest use in electronic、dental、and catalytic products、Occupational exposures occur in mining and dental laboratories、Used as a catalyst in many industries、General public exposures occur from automobile catalytic converters、dental restorations、and jewelry、[Nordberg、p. 1113-20]、Metal Extraction and Refining [Category: Industry]、Palladium is used in gold、silver and copper alloys in dentistry. Alloys are also used for bearings、strings、and balance wheels in watches. Palladium is used as a catalyst in the manufacture of sulfuric acid. In powder form it is used as a catalyst in hydrogenation. The sponge form is used for separation of hydrogen from a mixture of gases. Silver alloys are used for electrical contacts.、The automotive industry has used palladium in catalytic converters since 1974. ... In jewelry、palladium hardened with 4-5% ruthenium provides a light、white、strong、tarnish-free alloy for watch cases、brooches、and settings for gems.、...For alloy bearings、springs、balance wheels of watches、for mirrors in astronomical instruments、as catalyzer in manufacture of sulfuric acid and in other oxidizing processes.、Alloys for electrical relays and switching systems in telecommunication equipment、catalyst for reforming cracked petroleum fractions and hydrogenation、metallizing ceramics、"white" gold in jewelry、aircraft spark plugs、protective coatings.、For more Uses (Complete) data for PALLADIUM、ELEMENTAL (9 total)、please visit the HSDB record page.、Palladium is found mainly in catalytic converters and jewelry. It is also found in many electronics including computers、mobile phones、multi-layer ceramic capacitors、component plating、low voltage electrical contacts、and SED、OLED、LCD televisions. Palladium is also used in dentistry、medicine、hydrogen purification、chemical applications、and groundwater treatment. Palladium plays a key role in the technology used for fuel cells、which combines hydrogen and oxygen to produce electricity、heat and water. (L794)、Formulations、Preparations: Grade: CP (99.99%)、technical (99.0%)、Available as wire、leaf、powder、and single crystals.、Purified metals between 99.9% and 99.999% palladium are available for chemical or medical use as foil、granules、rod or wire.、General Manufacturing Information: Palladium: ACTIVE |
