Industrial Silicon Grades And Panel Pricing

There are many grades of industrial silicon, and there are eight national standards, from Si553 to Si1101.

This grade mainly represents the content of industrial silicon impurity elements Fe, Al, and Ca. In fact, in the market, there are non-standard categories such as out-of-grade silicon, 97 silicon, 99 silicon, and recycled silicon.Out-of-grade silicon generally refers to industrial silicon that does not reach the national standard 553# level and has a silicon content of about 98%; 97 silicon generally refers to the nominal silicon Industrial silicon with a silicon content of 97%, 99 silicon is a customary name in the industry, generally refers to industrial silicon with a silicon content of 99%, such as 541#, 531#, 621#, etc., which are often priced in total; while recycled silicon is mainly The silicon mud recovered from the silicon wafer production process is then smelted in an intermediate frequency furnace.

Although the silicon purity is generally high, it lacks activity and is mostly used in aluminum alloys or mixed in small quantities.
