Sintering of Titania Nanoceramics: Densification and Grain Growth

Two-step sintering (TSS) technique was applied to suppress the accelerated grain growth of TiO2 nanopowder in the final stage of sintering. While the grain size of full dense structure produced by conventional sintering ranges between 1-2 μm, the application of two-step sintering method led to a remarkable decrease of grain size down to ~250 nm.
