据保加利亚科学院金属矿冶研究所的资料,在研制对塑性要求较高的铝合金浇铸汽车零件的工艺时,铝合金中的铁含量不应超过0.3％。而标准铝合金中的铁含量为0.3—0.6％。显然这不符合工艺要求。为此,必需用化学纯硅替换使合金中铁比例高的结晶硅,也就是用微电子技术公司的生产废料替换结晶硅。该研究的所研制成用这些废料生产铝-硅中间合 According to the Bulgarian Academy of Sciences, Institute of Metals, Mining and Metallurgy, in the development of high plastic requirements of aluminum alloy casting automotive parts process, the aluminum content of iron should not exceed 0.3%. The standard aluminum alloy in the iron content of 0.3-0.6%. Obviously this does not meet the technical requirements. To do this, it is necessary to replace the crystalline silicon, which has a high proportion of iron in the alloy, with chemically pure silicon, ie to replace the crystalline silicon with microelectronics technology production waste. The study was developed to produce aluminum-silicon mesogens from these wastes
