WELCOME TO MISSISSIPPI SILICON Mississippi Silicon is the first domestic manufacturer of raw silicon metal built in the past 40 years and produces approximately 10% of all silicon metal used in the United States. In that time, similar plants have been built all around the world. We have made great progress since our launch in late 2015, and our facility directly competes with facilities in Europe, South Africa, Australia, Thailand, Malaysia and Brazil. We sell our silicon metal to customers that supply thousands of consumer, industrial and commercial markets in North America and around the world. LEARN ABOUT OUR PROCESS Silicon metal is a semi-conductive metalloid element that serves as a crucial component in thousands of products, from electronics to steel to automotive parts. Most people encounter products made with silicon metal several times every day without realizing it.
