“…Zircon (zirconium silicate) is used as a source raw material for production of chemically precipitated zirconia. There are some results showing that zirconia ceramics with controlled properties can also be synthesized from naturally occurring monoclinic zirconia — baddeleyite; however, it is not yet demonstrated that fine‐grained zirconia ceramics can be produced from this material. Use of baddeleyite provides a possibility of synthesis of zirconia ceramics without expensive and complicated chemical treatment of zircon.…”

For the first time, zirconia nanocrystalline powders were derived using baddeleyite as raw material by ultrafine milling. Powders containing 19 vol% of monoclinic phase were produced by milling of baddeleyite with addition of 11 mol% of CaO. Crystallite size of tetragonal and cubic phases in resulting powders is 3-5 nm and about 15 nm in the case of monoclinic phase. Typical agglomerate's size found by scanning electron microscopy ranges from~0.1 to 10 µm. Sintered ceramics with tetragonal zirconia content of 95 vol% and crystallite size of~50 nm are produced from the powders. *

“…In many experimental optimization problems, it is unusual to find only one answer that needs to be optimized; usually, several responses must be considered (Walters, 1999). Response surface methodology (RSM) is a set of mathematical techniques used to treat problems in which a response or responses of interest are influenced by several quantitative factors (Jaliliannosrati et al, 2013;Li et al, 2013;Wang et al, 2008). The initial purpose of these techniques is to design an experiment to provide reasonable values of the response variable and then determine an adequate mathematical model.…”

“…The performance of zirconia material increased by the stabilization as tetragonal phase using some additives such as Y 2 O 3, CaO, CeO 2 , MgO, etc. [1][2][3][4]. The use of 3 mol% yttria was main additive and it was proved that the zirconia ceramic has excellent strength and toughness [5].…”

In this study, nanocrystalline 3 mol % yttria-stabilized tetragonal zirconia polycrystalline (Y-TZP) ceramic was produced by sintering with a high-frequency induction heating (HFIH) system of granular powders obtained by ultrasonic spray pyrolysis (USP) at 600 °C. The granular nano-sized powders (10-30 nm) were micron in size (average size: 700 nm), spherical in shape and amorphous. The influences of the HFIH sintering temperature (1400-1600 °C), applied current time (60-300 sec.) and the mechanical pressure (10 MPa and 20 MPa) on the final density and grain size of the products were investigated. The amorphous granular Y-TZP powders compressed with the HFIH system allow very rapid condensation in the tetragonal phase at high density and avoid grain growth. High density (relative density over 95) nanocrystalline Y-TZP ceramic with ∼70 nm size could be obtained from the simultaneous application of 20 MPa pressure and an induced current within 300 sec. of sintering time at 1500 °C. In this condition, the sample’s maximum hardness and fracture toughness values were reached at 14.9 GPa and 3.8 MPa·m1/2, respectively. Y-TZP powders produced in nano-micro structure with the USP system were sintered with the HFIH system and rapid production was achieved by preventing grain growth.
