数据库记载的用途

• 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.
