Stage 1 of 12Inputs & materials
Raw materials
Silica sand, chemicals, and the elements chips are built from.
What happens here?
The elemental inputs are sourced and refined into feedstock — high-purity silica reduced to metallurgical-grade silicon, plus the many process gases, chemicals, and rare materials the rest of the chain consumes.
