High temperature behaviour of a zircon ceramic
The high temperature properties of a sintered zircon material has been tested up to 1200°C. A significant creep rate is observed, mainly attributed to the presence of glassy phase. The sub-critical crack growth measured in double torsion showed that above 1000°C, the crack velocity is reduced either by stress relaxation or by crack healing. The thermal shock analysis under a heat exchange coefficient of 600 W/m2/K showed a regular decrease rather that a sudden fall off of properties.
