金屬硅和原生硅有什么區別?主要用于什么?

金屬硅和原生硅有什么區別?主要用于什么?

金屬硅和原生硅,這兩種金屬大家了解嗎?坤鑫達小編為您做詳細介紹!金屬硅又稱結晶硅或工業硅,其主要用途是作為非鐵基合金的添加劑。 硅是非金屬元素,呈灰色,有金屬色澤,性硬且脆。硅的含量約占地殼質量的26%;原子量為28.80;密度為2.33g/m3;熔點為1410。

金屬硅的用途:金屬硅(Si)是工業提純的單質硅,主要用于生產有機硅、制取高純度的半導體材料以及配制有特殊用途的合金等。

(1)生產硅橡膠、硅樹脂、硅油等有機硅

硅橡膠彈性好,耐高溫,用于制作醫療用品、耐高溫墊圈等。

硅樹脂用于生產絕緣漆、高溫涂料等。

硅油是一種油狀物,其粘度受溫度的影響很小,用于生產***潤滑劑、上光劑、流體彈簧、介電液體等,還可加工成無色透明的液體,作為防水劑噴涂在建筑物表面。

(2)制造高純半導體

現代化大型集成電路幾乎都是用高純度金屬硅制成的,而且高純度金屬硅還是生產光纖的主要原料,可以說金屬硅已成為信息時代的基礎支柱產業。

(3)配制合金

硅鋁合金是用量較大的硅合金。硅鋁合金是一種強復合脫氧劑,在煉鋼過程中代替純鋁可提高脫氧劑利用率,并可凈化鋼液,提高鋼材質量。硅鋁合金密度小,熱膨脹系數低,鑄造性能和抗磨性能好,用其鑄造的合金鑄件具有很高的抗擊沖擊能力和很好的高壓致密性,可大大提高使用壽命,常用其生產航天飛行器和汽車零部件。

硅銅合金具有良好的焊接性能,且在受到沖擊時不易產生火花,具有防爆功能,可用于制作儲罐。

鋼中加入硅制成硅鋼片,能大大改善鋼的導磁性,降低磁滯和渦流損失,可用其制造變壓器和電機的鐵芯,提高變壓器和電機的性能。

隨著科學技術的發展,金屬硅的應用領域還將進一步擴大。

坤鑫達主要產品有:硅碳球、增硅劑、碳化硅、金屬硅粉、硅微粉、包芯線等,我公司產品質量穩定可靠,均可按用戶要求進行品質保證,現貨供應!詳情了解登錄:http://www.centralpennbldgsvs.com
