Glass ceramics are made of small grains surrounded by a glassy phase and have properties in between those of glass and ceramics.
Crystal structure of ceramics ceramics contain the same imperfections in their crystal structure as metals vacancies displaced atoms interstitialcies and microscopic cracks internal flaws tend to concentrate stresses especially tensile bending or impact hence ceramics fail by brittle fracture much more readily than metals.
Pdf over the last decade it has been observed that there is an increasing interest in the ceramic materials in dentistry.
Advanced structural ceramics are being used or have the potential to be used in a large variety of applications ferber and tennery 1991 american ceramic society website some of the primary application areas are listed in table 1 this is not intended as a complete list but rather a sampling of some of the applications with the greatest potential and or the greatest interest.
