Reinforcing and toughening alumina/titania ceramic composites with nano-dopants from nanostructured composite powders

The effect of heat treatments applied to superstructure porcelain on the mechanical properties and microstructure of lithium disilicate glass ceramics

“…They stated that this situation was associated with the porosity and density of the material. In other studies similar to this study, they also reported that the hardness increased as the density of material increased but its porosity decreased [40][41][42][43] . Hardness, which affects the finishability, polishability, and occlusal wear resistance of restorative material, is an important property 44) .…”

Effects of multiple firings on the mechanical properties and microstructure of veneering ceramics for zirconia frameworks

“…Some investigations concerning ceramic materials have revealed that the porosity is lower and the density is higher for the ceramic bulk, the hardness is higher. [27][28][29] It may be explained by the densification mechanism of liquid-phase sintering. 30 In clinical situations, hardness is also an important property because it is a factor affecting the finishability, polishability, and occlusal wear resistance of a material.…”

Effect of TiO2 Nanoparticles on Properties of Silica Refractory

“…In order to eliminate the above troubles while use in industrial applications, nanotitania is used as mineralizer 14 to reduce the calcium oxide binder, which prevents the degradation, loss of refractoriness, and thermal expansion of fused silica refractory bricks in furnace environments. The incorporation of nanometal oxides such as TiO 2 , 15 SiO 2 , 16 ZrO 2 , 17 and MgO 18 into the refractories enhances the physico‐chemical and thermo‐mechanical properties of refractories and their composites 19 …”
