Effect of sintering time on biaxial strength of zirconium dioxide
Hjerppe J et al. - No statistically significant difference (p > 0.05) was found between the groups in terms of sintering time or thermocycling. The biaxial flexural strength of the groups varied from 995 MPa to 1127 MPa. Surface microhardness varied from 1478 to 1532. The relative amount of the monoclinic phase was higher when zirconia was thermocycled and stored in water compared to control discs, which had no monoclinic phase at all. [more...]
