Silicon - High Precision Machining - Insaco

Silicon is well known as a key component of electronic devices and also of solar cells. For these appliions, the silicon must be purified from its initial form. Silicon is certainly a readily available raw material since it is actually the third most abundant element on Earth after only iron and oxygen, and is handy to isolate from common sand by reduction with coke in the presence of iron.

Silicon Carbide: a Love-Hate Relationship | EE Times

Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”
