The Effect of Processing Parameters on the Mechanical Properties of Calcia-Stabilized Zirconia (CSZ) for Dental Use

Three different compositions with 9%, 12%, and 15% of calcia-stabilised zirconia (CSZ) were prepared from commercially available submicron-sized powders by cryo-milling. The influence the sintering conditions, temperature, dwell time varied as 1400, 1500, 1600 °C, at durations 4, 3, 2 h on mechanical properties is studied. SEM XRD studies performed pellets obtained hydraulic pressing in a uniaxial press 13 tonnes. effect holding temperature properties, such hardness, flexural strength, compressive strength (in universal testing machine), CSZ It seen that, increase calcia, increase, until full stabilisation created due to calcium ion substitution ionic vacancies. An has positive °C strengths CSZ. Mechanical through cryo-milling sintered high shorter found suitable for dental applications.
