bismuth alloy造句

• There is very little life-cycle information on other bismuth alloys or compounds.
• The fission products are then removed from the bismuth alloy in a separate step, e . g . by contact to a LiCl melt.
• For example, bismuth in stomach medicine is hopelessly scattered ( dissipated ) and therefore impossible to recover, while bismuth alloys can be easily recovered and recycled.
• As the toxicity of lead has become more apparent in recent years, there is an increasing use of bismuth alloys ( presently about a third of bismuth production ) as a replacement for lead.
• One exception is arising due to the market introduction of lead free shotshell ammunition loaded with steel or alloy ( e . g ., bismuth alloy ) pellets instead of more traditional lead-based pellets.
• Some bismuth alloys, such as Bi35-Pb37-Sn25, are combined with non-sticking materials such as mica, glass and enamels because they easily wet them allowing to make joints to other parts.
• Taking the US as an example, 884 tonnes of bismuth were consumed in 2010, of which 63 % went into chemicals ( including pharmaceuticals, pigments, and cosmetics ), 26 % into metallurgical additives for casting and galvanizing, 7 % into bismuth alloys, solders and ammunition, and 4 % into research and other uses.
• In 1984 a bismuth alloy supplied by the plant to a company in Germany was found to be radioactive : alpha radiation was found to be emitted by-products of the smelting process due to the presence of polonium 210 ( a radioisotope with a half life of about 140 days ), thought to be produced via radioactive decay of naturally occurring isotopes in tin-bearing ore bodies such as granite.
