金屬硅 Silicon Metal
金屬硅又稱結晶硅或工業硅,是由石英和焦炭在電熱爐內冶煉成的產品,主成分硅元素的含量在98%左右(近年來,含Si量99.99%的也包含在金屬硅內),其余雜質為鐵、鋁、鈣等。
硅粉,為銀灰色或深灰色粉末,具有金屬光澤。它具有熔點高、耐熱性好、電阻率高、抗氧化效果好等特點,是耐火澆注料、塞棒等耐火工業的基本原料。
Silicon powder,it is silver gray or dark gray powder with metallic luster. With the characteristic of high melting point, good heat resistance, high resistivity and high antioxidant effect, it is the basic raw material to refractory industry,such as refractory castables,stopper rod.
