Combustion synthesis of yttria


Fine-particle, sinter-active yttria has been prepared by combustion of a redox compound, Y(N2H3COO)3·3H2O and mixtures of Y(N2H3COO)3·3H2O–NH4NO3 or NH4ClO4 as well as yttrium nitrate and hydrazine-based fuels. The fineparticle nature of the combustion-derived yttria has been investigated using powder density, particle size and BET surface area measurements. The uniaxially, cold-pressed fine-particle yttria when sintered at 1450–1500 °C achieved 98% theoretical density and showed a fine-grain (1–2 µm) microstructure.
