Abstract
The "transparent" ceramics are interesting because they have the potentiality of many applications. The transparent ceramics are generally got as amorphous based upon glass components, silicates, germinates, borates etc. Taking the super rapid quenching method, amorphous materials might be got in composites containing no glass component. But the amorphous fabricated by super rapid quenching may limit the shape to film. In this study, we have fabricated successfully amorphous materials from HfO2-Al2O3-GdAlO3 composites without glass components. Furthermore, we have got nano-structured bulk ceramics by annealing the amorphous ceramics.
