Abstract

Equilibrium calculations were used to optimize conditions for the chemical vapor deposition (CVD) of zirconia. The results showed zirconia formation would occur at high oxygen to zirconium atomic ratios (> 4), low hydrogen to carbon ratios (< 10), low pressures (< 105 Pa) and high temperatures (> 800 °C). Using these calculations as a guide, single-phase monoclinic zirconia coatings were deposited onto 2-cm diameter α-alumina substrates. The maximum growth rate achieved was 2.46 mg cm^{- 2} h^{- 1}.
