Role of MgF2 on properties of glass–ceramics
Source abstract
Abstract
Formation of machinable glass–ceramic in the system MgO–SiO2–Al2O3–K2O–B2O3–F with and without addition of MgF2 has been investigated. Crystallization of glass sample was done by controlled thermal heat treatment at nucleation and crystallization temperatures. The results showed that MgF2 in high concentration had a synergistic effect and enhanced the formation of interlocked mica crystals. Non-isothermal DTA experiments showed that the crystallization activation energies of base glasses were changed in the range of 235–405 kJ/mol, while the crystallization activation energies of samples with addition of MgF2 were changed in the range of 548–752 kJ/mol.
