4. Strategic Importance Of Silicon-28
Silicon-28, constituting 92.2% of natural silicon, is critical for next-gen quantum computing and advanced semiconductors. ASP’s plan to scale production aligns with rising demand in electronics and space applications, positioning the company for long-term growth.
