Influence of glass phase on Al2O3 fiber-reinforced Al2O3 composites processed by slip casting

Effect of Heat Treatment Schedules and Glass Powder Particle Size on Glass Infiltration in Porous Alumina Preforms

“…In glass infiltrated ceramics, the three‐dimensional network of interlacing ceramic and glass improved fracture toughness. Many studies have been carried out on all‐ceramic dental materials processed by melt infiltration of glass . While studies have reported effect of ceramic (alumina) powder particle size on glass infiltration, very few studies have reported influence of glass powder characteristics and infiltration condition (temperature and time) on glass infiltration in sintered porous ceramic matrix .…”

“…Many studies have been carried out on all-ceramic dental materials processed by melt infiltration of glass. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] While studies have reported effect of ceramic (alumina) powder particle size on glass infiltration, very few studies have reported influence of glass powder characteristics and infiltration condition (temperature and time) on glass infiltration in sintered porous ceramic matrix. 26 This study reports work carried out to examine the influence of heating rate during glass infiltration, glass particle size and the soaking time on the infiltration behavior of lithium borosilicate glass in porous alumina preforms.…”

Effect of Pore Characteristics in Slip Cast Alumina on Glass Infiltration and Mechanical Properties of the Composites

“…[11][12][13][14][15][16][17][18][19][20][21][22] Processes that depend on development of dental crowns by directly building material on the model of patient's oral cavity do not provide any possibility of making enlarged crowns of controlled dimensions such that when sintered, they shrink to fit on the prepared tooth of the patient.

Thus, such processes depend on building the crown of same dimensions as needed to fit the patient, which necessitates sintering of ceramic performs at a temperature at which shrinkage is minimal.…”
