Porous bioceramics called scaffolds have been studied for bone replacement and repair, with properties that meet the functionality and integration between the biomaterial and the biological system. Al2O3 and Al2O3/ZrO2 bioceramics are recognized as biomaterials due to their improved mechanical properties, high chemical stability and biocompatibility when compared to other materials. Howev…
The sintering flash technique (SF), presented in the literature in the last decade, consists of the electric field application in the sample concomitant with increasing the temperature of the furnace during the sintering. Materials with negative temperature coefficient have their electrical resistance inversely proportional to the temperature. Thus, at a given temperature, a significant e…
A new concept of extensively studied materials involves nanostructured materials, which can be defined as systems that contain at least one microstructural characteristic with nanometric dimensions. These nanostructures may be responsible for particular characteristics of the nanocomposites in their properties such as increased hardness, fracture mode to change from transgranular intragra…

The search for alternative treatments involving the application of biomaterials in tissue engineering and regenerative therapies is becoming increasingly common due to the increase in bone tissue-related diseases. In this context, the development and use of Additive Manufacturing (AM) technologies, popularly known as 3D printing, in the processing of biomaterials has been increasingly res…
Alternative techniques to conventional sintering have been studied aiming to control microstructure and grain growth, in addition to a lower energy consumption. Among these techniques flash sintering (FS) can be highlighted. This process consists of exposing a material in direct contact with two electrodes, by which a high-intensity electric field is applied simultaneously to conventional…

Zirconia (ZrO2) scaffolds are widely used in hard tissue engineering primarily due to their intrinsic properties, such as hardness, wear resistance, and aesthetics. For bone regeneration, the surface of these scaffolds can be modified to improve their surface properties and achieve bioactivity, for instance, using calcium phosphate (CaP) coatings. These coated scaffolds can be combined wi…
In the last decade the flash sintering technique (FS) was presented in the literature. This technique was distinguished by sintering materials in a few seconds and at much lower temperatures than conventional ones, from the application of electric field during the heating of the samples. The aim of the present work is to automate, for the first time, the control of SF parameters such as f…
