Recent nanoscale (e.g. sol-gel) technology has, however, made possible the production of polycrystalline transparent ceramics such as transparent alumina and alumina compounds for such applications as high-power lasers.
Teknologi nano (misalnya sol-gel) terbaru, bagaimanapun, memungkinkan produksi keramik transparan polikristal seperti alumina transparan dan senyawa alumina untuk aplikasi semacam laser berenergi tinggi.
