Crystallization behaviour and hardness of glass ceramics rich in nanocrystals of ZrO2

Influences of multiple firings and aging on surface roughness, strength and hardness of veneering ceramics for zirconia frameworks

“…Another study has also shown the porosity of these veneering ceramics fired 10 times to be less pronounced than that of those fired twice [2]. The results of this previous study are consistent with those of several investigations that showed that these surfaces are more porous, rougher, or both [50][51][52]. The increase in hardness is probably a very relevant piece of information for attempts to increase resistance to fatigue and prevent premature material failures.…”

Effect of zinc oxide and zirconia on structure, degradability and in vitro bioactivity of wollastonite

“…Hong [31] studied the effect of ZrO 2 on the physical and mechanical properties of wollastonite, and the properties of wollastonite can be obviously improved by these additives. S. Banijamali et al [32][33][34][35] Ni [37] synthesized CaSiO 3 powder by a chemical precipitation method. P. Siriphannon [38] fabricated CaSiO 3 from coprecipitated powder using NaOH as precipitant.…”

Synthesis and Sintering Studies of Magnesium Aluminum Silicate Glass Ceramic

“…MAS glass ceramic materials have been prepared by controlled crystallization in which a large number of tiny crystals rather than few bigger single crystals have been grown (Margha, et al, 2009). Controlled crystallization or heat treatments generally consist of a two-stage heat treatment, namely a nucleation stage and crystal growth stage.…”
