Enhanced densification of In2O3 ceramics by presintering with low pressure (5 MPa)

Abstract

Sintering of In2O3 has been carried out in air to full density, Because of the difference in densification between the agglomerates and the matrix, large interagglomerate pores were observed to form at the initial stage of sintering. Such pore formation could be prevented by applying a small external pressure which resulted in the beneficial rearrangement of agglomerates.
