In this work, micro rod arrays of 50 um and 200 um in diameter, respectively, were fabricated by 316L metal injection molding. Acryl sacrificial mold was used for the 50 um rod array. Aspect ratios were about 8 and 6 in 50 um and 200 um rod arrays, respectively and the bending of the rods occured due to high aspect ratio in debinding and sintering steps. Also, severe grain growth occurred at rod surface by sintering for 3 hrs at 1300°C and the average size was measured to be about 70 um.

Micro-scale plake-like SrTO3 particles were synthesized by two routes of topochemical conversion. One is by growing on Sr3Ti2O7 (S3T2) core particles in molten salt condition, and the other is from the layer-structured SrBi4Ti4O15 (SBT) precursor in a KCl medium. The effects of the morphology and size of the precursor to platelet SrTiO3 crystals were studied. X-ray diffraction analysis revealed that the crystallographic {010} plane of SBT was converted into the pseudo-cubic {001} plane of SrTiO3. The polycrystalline SrTiO3 particles from BST precursor exhibited a plate-like shape with 10-15μm in length and a high aspect ratio, and were more suitable for preparing textured ceramics by templated grain growth process than the platelets from the S3T2 precursors.
