The process of producing metallic silicon is the process of deoxidizing and reducing the raw materials of silicon oxide, such as silica, dolomite, etc.
Both Silicon 553 with without Oxygen are with a Si content of more than 98.5% can be called industrial silicon, or silicon metal. Among them, Silicon metal 553 is a common and widely used model. Its purity is more than 98.5% Si metal. Silicon Metal 553 Oxygen and Si 553 without Oxygen are 2 models of it.
Silicon is the second most abundant element on earth, the first being oxygen. At the same time, silicon and oxygen can easily form silicon oxide. In the process of producing metallic silicon, the purity of silicon becomes higher and higher, and other impurities become smaller and smaller. However, in addition to iron, aluminum, and calcium, metal silicon also contains small amounts of other impurity elements.
Silicon Refining
To remove these impurities, the raw materials of silicon metal need to be strictly in accrodance with standard. Among them, oxidative refining is a common method. Under the same pressure and temperature, calcium has the greatest affinity for oxygen, followed by aluminum and then silicon. In the process of smelting metallic silicon, adding an oxygen blowing step, also known as oxygen blast or oxygen blow process. It can achieve the purpose of removing impurities. The one that has been blown is Si Metal 553 with Oxygen, the other one is Si #553 no oxygen.
Applications of Silicon 553 with without Oxygen
Si#553 has a wide range of applications and uses, both with and without oxygen. However, in different fields, their roles are also different. Here are some common applications:
Silicon metal oxygen has lower impurities. In the metallurgical industry,it is usually to make special alloys, such as manganese-silicon alloy, chromium-silicon alloy, etc. In the electronics industry, 553 metal silicon oxygen has excellent conductive properties, it has large applicatioin in electronic components.
Si metal 553 no oxygen is often used in the manufacture of acid and alkali corrosion resistant materials due to its excellent corrosion resistance. Si 553 no oxygen can also to make capacitors to provide isolation and protection of electronic components.
By understanding the difference between silicon metal 553 with and without oxygen, we can see the differences in their applicability and characteristics. It can be used in alloy manufacturing and the electronics industry through oxygen-, while 553 metal silicon without oxygen is mainly used in fields such as anti-corrosion materials and capacitors. Whether it is 553 metal silicon with or without oxygen, it plays an important role in their respective fields.
