用鎂還原二氧化矽可得無定形矽。用碳在電爐中還原二氧化矽可得晶體矽。電子工業中用的高純矽則是用氫氣還原三氯氫矽或四氯化矽而製得。 The changeover to cleaner Electrical power has put the spotlight on critical minerals and scarce earth components. These are typically important for manufacturing the carbon-no cost and reduced-carbon technologies that can help us to maneuver from fossil fuels... https://demo.jcow.net/feed/view/141848
