Hot Isostatic Pressing of SnO2 Prepared by the Hydrazine Method (特集 ナノ構造制御と新機能発現) Hot Isostatic Pressing of SnO_2 Prepared by the Hydrazine Method
Reactive Snot powders have been prepared by the hydrazine method. Their individual particles tend toward a hexagonal morphology with increasing temperature. Well-densified SnO<SUB>2</SUB> ceramics (99.8% of theoretical) with an average grain size of 0.9μm have been fabricated by hot isostatic pressing for 2 h at 900°C and 196 MPa. Their Vickers hardness and bending strength are -14.4 GPa and -200 MPa, respectively. They exhibit an electrical conductivity of -5 × 10<SUB>-3</SUB> S⋅cm<SUP>-1</SUP> at room temperature.
