The major end uses of zircon are refractories, foundry sands (including investment casting), and ceramic opacification.
Zirconium alloys are used as nuclear reactor core components and cladding materials for nuclear fuels because four stable isotopes, 90 Zr, 91 Zr, 92 Zr, 94 Zr, show low cross-sections for neutron capture, with 90 Zr being the lowest neutron absorbent. Rates of fuel burn-up and neutron fluxes can be determined by measuring Zr isotope ratios.
