Sintering of ZrSe2 has been investigated by hot-pressing at 800°-1450°C and by isothermal, normal sintering at 1420°-1480°C in nitrogen atmosphere also. The starting materials, ZrSe2 and ZrSe3 were synthesized by a chemical-transport method. Decomposition and degradation of ZrSe3 into ZrSe2 with lower selenium content occurred during 800°-1000°C in hot-pressing. Density and compressive strength of the sintered body increased on hot-pressing above 1150°C. The compact started from ZrSe3 reached a maximum density, 98% theoretical and a maximum compressive strength, 1850kg/cm2, under the hot-pressing conditions: 1350°C, 130kg/cm2, 1h. Degradation of ZrSe3 was applicable for an activated sintering in hot-pressing of ZrSe2. Shrinkage and densification occurred also in isothermal, normal sintering of ZrSe2. Progress in sintering of ZrSe2 was accompanied with release of Se and with increase in non-stoichiometry in ZrSe2 to lesser Se/Zr ratio. It was suggested that the sintering process of ZrSe2 was governed by diffusion mechanisms.
