Young's modulus evolution during sintering and thermal cycling of pure tin oxide ceramics

Popis výsledku v původním jazyce

Pure tin oxide (SnO2) ceramics is well known for its bad sinterability, more precisely for the difficulty to densify without additives by conventional pressureless sintering. This is related to the fact that the sintering mechanisms in pure tin oxide ceramics are non-densifying (surface diffusion at low temperature and evaporationcondensation at high temperature). On the other hand, for the same reason, pure tin oxide ceramics is a very unusual model system that can be used to demonstrate the effects of microstructural changes on effective properties without the otherwise dominating effect of changes in porosity. In this paper we show that pure tin oxide ceramics uniaxially pressed at 50 MPa, pre-sintered at 500 degrees C and re-sintered at 1000, 1200 and 1400 degrees C exhibit relative Young&apos;s modulus increases of 30, 70 and 120 % while the porosity remains essentially constant at a value of 51.6 +/- 0.7 %.
