“…[142] Optically anisotropic ceramics are even more challenging, as the transparency decreases drastically as grain size increases, and alumina, [143][144][145][146] tetragonal zirconia, [147] or hydroxyapatite [148] have been synthesized with improving success. Compared to standard free sintering in vacuum followed by HIP, the definite advantages of FAST/SPS are: (i) one single set-up required for densification and (ii) shortening of the process cycle.…”

Field-assisted sintering technology/Spark plasma sintering is a low voltage, direct current (DC) pulsed current activated, pressure-assisted sintering, and synthesis technique, which has been widely applied for materials processing in the recent years. After a description of its working principles and historical background, mechanical, thermal, electrical effects in FAST/SPS are presented along with the role of atmosphere. A selection of successful materials development including refractory materials, nanocrystalline functional ceramics, graded, and non-equilibrium materials is then discussed. Finally, technological aspects (advanced tool concepts, temperature measurement, finite element simulations) are covered.

“…As the nanodimensional and nanocrystalline calcium orthophosphates tend to agglomerate at heating (Fig. 8) [313,[593][594][595], normally a low-temperature [169,371] and/or a rapid consolidation [169,258,323,[596][597][598][599][600][601][602] techniques must be employed. The low-temperature approach comprises gel hardening (at 4 ºC) [371] and uni-axial pressing at 150 -200 ºC [169].…”

“…The low-temperature approach comprises gel hardening (at 4 ºC) [371] and uni-axial pressing at 150 -200 ºC [169]. The rapid consolidation techniques comprise spark plasma sintering [169,258,323,[596][597][598][599], pressure sintering [597] and microwave sintering over the temperature range 1000 -1300 ºC, using a rapid sintering schedule [600][601][602].…”

Nano-sized particles and crystals play an important role in the formation of calcified tissues of various animals. For example, nano-sized and nanocrystalline calcium orthophosphates in the form of apatites of biological origin represent the basic inorganic building blocks of bones and teeth of mammals. Namely, according the recent developments in biomineralization, tens to hundreds nanodimensional crystals of a biological apatite are self-assembled into these complex structures. This process occurs under a strict control by bioorganic matrixes. Furthermore, both a greater viability and a better proliferation of various types of cells have been detected on smaller crystals of calcium orthophosphates. Thus, the nano-sized and nanocrystalline forms of calcium orthophosphates have a great potential to revolutionize the hard tissue-engineering field, starting from bone repair and augmentation to controlled drug delivery systems. This review reports on current state of the art and recent developments on the subject, starting from synthesis and characterization to biomedical and clinical applications. Furthermore, the review also discusses possible directions for future research and development.

“…Similar to the mineral found in hard tissues (Vallet-Regi and Gonzalez-Calbet, 2004), it has been the most useful processing material for a variety of biomedical applications (Huang, 2007;Wu, 2015). In addition, nanosized hydroxyapatite shows improved densification and sinterability due to its high surface energy (Eriksson, 2011;Bianco, 2009 (Arita et al, 1995), co-precipitation method (Akao, 1981;Kong, 2002), hydrothermal method (Zhang and Vecchio, 2007), sol-gel process (Wang and Shaw, 2009) and microwave processing (Yang et al, 2002) method. In the present study, preparation and characterization of precipitated nanosized hydroxyapatite were carried out using the method of chemical co-precipitation.…”
