Silicon yachitsulo, yomwe imadziwikanso kuti crystalline silikoni kapena silicon yamakampani, imagwiritsidwa ntchito makamaka ngati chowonjezera pazitsulo zopanda chitsulo.Silicon yachitsulo ndi chinthu chomwe chimasungunuka kuchokera ku quartz ndi coke mu ng'anjo yamagetsi.Chigawo chachikulu cha silicon zili pafupifupi 98% (zaka zaposachedwa, 99.99% ya Si zomwe zili mkati zimaphatikizidwanso mu silicon yachitsulo), ndipo zonyansa zotsalira ndi chitsulo ndi aluminiyamu.calcium, etc.
