Products Description
The silicon metal 553 has a very widely use. It's one of the most useful metals that can be widely used in industry. It can be a origin material to produce other industrial materials. Otherwise,it can be used by only itself.

Products cooperation pictures
1. The silicon metal 553 looks like grey stones and it's same to other kinds of types silicon metal. So it is very hard to distinguish the silicon metal 553 with other kinds of types silicon metal,and even other metals.,such as iron.
2. Although it's very hard to distinguish the silicon metal 553 with other meatals,we can sure the silicon metals 500 by seeing it's elements of Si. It's the most easy way to sure that if a metal is silicon metal.
3. Our company produce the silicon metal 553 and other kinds of metals and alloys. We can promise that the elements of Si of our silicon metal can get the international standard.
4. One way to produce the silicon metal 553：Before releasing the silicon melt, refining gas is continuously introduced into the ladle. The refining gas is a mixed gas of air, oxygen, oxygen-enriched air, h2o, h2, ar, and n2, and the flow rate of the refining gas is 10m /h, and then release the silicon melt in the submersible furnace into the lifting bag, and at the same time heat and preserve the silicon water in the lifting bag. The heating method is microwave heating, and the control temperature is 1500°C. After the initial temperature rise, Add refining agent to the bag. The refining agent is a mixture of sio2, cao, al2o3, mgo, nao, caf2, bao, li2o and lif. Then blow air outside the furnace and make slag for refining. After the refining outside the furnace is completed, carry out slag silicon Separate and then pour to obtain high-purity 553 metallic silicon.
