In this paper, the compact SiO2-B2O3-Al2O3-MgO-F machinable ceramics were prepared through melt-cast and sintering method. The phase composition and microstructure of the ceramics were analyzed and observed using XRD and SEM, and the relationship between processing and microstructure were discussed. The results showed that, after the heat treatment, the main phase of the ceramics changed from fluorophlogopite (mica like) to fluoramphibole (rod like). When the crystallization temperature at 950°C, the nuclei growth rate of the mica glass-ceramics was higher. Meanwhile, a small quantity of forsterite (Mg2SiO4) was also crystallized out in the process. The best heat treatment process was nucleated at 630°C for 2h and crystallized at 950°C for 2h.

Main Crystalline Phase

The Na2O-CaO-SiO2-MgO-Al2O3-ZnO glass-ceramics was prepared from the phosphorus slag as main primary raw materials by melt quenching technique. The effects of K2O and Al2O3 on crystallization behavior and structure of glass-ceramics were investigated by DSC, XRD and SEM. It is shown that the main crystalline phase is combeite (Na4Ca4(Si6O18)) in glass-ceramics. K2O and Al2O3 do not change the main crystalline phase of glass-ceramics, but K2O increases the crystallization temperature, Al2O3 increases the crystallization temperature, obviously decreases the grain size. The K2O isometric replaces Na2O at the same time the Al2O3 isometric to replace SiO2, reduced the grain size.

Influence Of Crystallization

ABSTRACTThe influence of the crystallization condition - temperature and time - on the structure of poly (vinylidene fluoride chlorotrifluoroethylene), P(VDF-CTFE), was studied using DSC and XRD. The DSC results of all studied polymers show three peaks. One peak, which is associated with crystallization temperature, represents the appearance of unstable phase in the polymers. Both XRD and DSC data indicate the coexistence of different phases in the polymers, which may be the reason for the high electrostrictive performance obtained in the polymers.
