Sinter-crystallization in the diopside–albite system Part II. Kinetics of crystallization and sintering

چکیده
The formation of intragranular pores, induced by diopside crystallization in diopside–albite glasses, was highlighted in a previous study and here confirmed by SEM observation. The sinter-crystallization kinetics of four glass compositions, labelled G1, G2, G3 and G2-Cr, characterized by the formation of induced crystallisation porosity, PCR, was investigated. The activation energies of crystallisation, EC, and sintering, ES, were evaluated by differential thermal analysis (DTA) and by contact differential dilatometer in non-isothermal conditions, respectively. The results highlighted that the kinetics of the crystallization process was not influenced by the PCR formation and that the EC values are in a

Properties of sintered glass-ceramics in the diopside–albite system
A series of sintered glass-ceramics belonging to the system diopside–albite, forming by surface crystallization 30, 50 and 65% diopside, was investigated. In order to study the effect of bulk crystallization on the sintering a 0.7% of Cr2O3 as nucleation agent was added in one of the compositions. The crystallization was evaluated by DTA and density measurements and the degree of densification ...
متن کاملSinter-crystallisation in the diopside–albite system Part I. Formation of induced crystallisation porosity
The sinter-crystallisation was investigated in three model glasses (G1, G2 and G3) belonging to the diopside–albite system and forming between 30 and 60% diopside, respectively. The effect of bulk crystallisation on the sintering was studied by the addition of 0.7 wt.% Cr2O3 as nucleating agent to the G2 glass. The degree of sintering was evaluated by the variation of the apparent density while...

diopside (CaO·MgO·2SiO2) and wollastonite (CaO·SiO2) glass-ceramics, forming ∼60% crystal phase and ∼40% albite-like Na2O·Al2O3·6SiO2) residual glass were studied. Two other diopside glass-ceramics with higher Na2O and Al2O3 content were also investigated. The phase formation was estimated by DTA, XRD and pycnometry, while the densification process was evaluated by porosity variations, ilatomet...
متن کاملSinter-crystallization of a glass obtained from basaltic tuffs
Glass-ceramic materials, obtained by sinter-crystallization of melted alkaline-olivine basaltic tuffs, were investigated. The kinetics of bulk crystallization was evaluated by differential thermal analysis (DTA) at different heating rates. The phase formation and the sintering behavior of glass powders (<75 lm) were studied in air and in nitrogen atmospheres by DTA and dilatometry, respectively...

Highly porous wollastonite-diopside glass-ceramics have been successfully obtained by a new gel-casting technique. The gelation of an aqueous slurry of glass powders was not achieved according to the polymerization of an organic monomer, but as the result of alkali activation. The alkali activation of a Ca-Mg silicate glass (with a composition close to 50 mol % wollastonite-50 mol % diopside, w...
