金属硅</p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
<span style="font-weight: 700;">金属硅</span>又称结晶硅或工业硅，其主要用途是作为非铁基合金的添加剂。金属硅是由石英和焦炭在电热炉内冶炼成的产品，主成分硅元素的含量在98%左右（近年来，含Si量99.99%的也包含在金属硅内），其余杂质为铁、铝、钙等。我厂也生产80硅和95硅。</p>

</p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
1.工业硅粉广泛的应用于耐火材料、粉末冶金行业中，以提高产品的耐高温，耐磨损和抗氧化性。其产品被广泛的应用于炼钢炉、窑炉、窑具中。</p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
</p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
2.在有机硅化工行业，工业硅粉是有机硅高分子合成的基础原料，如用于生产硅单体、硅油、硅橡胶防腐剂，从而提高产品的耐高温性、电绝缘性、耐腐蚀性、防腐蚀性、防水等特性</p>

</p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
3.工业硅粉经拉制成单晶硅，加工而成的硅片被广泛应用于高科技领域，是集成电路，电子元件必不可少的原材料。</p>

</p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
4.冶金铸造行业中，工业硅粉作为非铁基合金添加剂、硅钢合金剂，从而提高钢淬透性。工业硅粉也可应用于某些金属的还原剂，用于新型陶瓷合金等。</p>

<span style="font-weight: 700;">二：金属硅的分类</span></p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
</p>
<p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;">
通常按金属硅成分所含的铁、铝、钙三种主要杂质的含量来分类。按照金属硅中铁、铝、钙的含量，可把金属硅分为553、441、411、421、3303、3305、2202、2502、1501、1101等不同的牌号。</p>
