padding: 0px; line-height: 1.5; clear: both;"> &nbsp;</p> <p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;"> 1.工業硅粉廣泛的應用于耐火材料、粉末冶金行業中，以提高產品的耐高溫，耐磨損和抗氧化性。其產品被廣泛的應用于煉鋼爐、窯爐、窯具中。</p> <p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;"> &nbsp;</p> <p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;"> 2.在有機硅化工行業，工業硅粉是有機硅高分子合成的基礎原料，如用于生產硅單體、硅油、硅橡膠防腐劑，從而提高產品的耐高溫性、電絕緣性、耐腐蝕性、防腐蝕性、防水等特性</p> <p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;"> &nbsp;</p> <p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;"> 3.工業硅粉經拉制成單晶硅，加工而成的硅片被廣泛應用于高科技領域，是集成電路，電子元件必不可少的原材料。</p> <p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;"> &nbsp;</p> <p style="margin: 0px; padding: 0px; line-height: 1.5; clear: both;"> 4.冶金鑄造行業中，工業硅粉作為非鐵基合金添加劑、硅鋼合金劑，從而提高鋼淬透性。工業硅粉也可應用于某些金屬的還原劑，用于新型陶瓷合金等。</p> <p style="margin: 0px;
