Transparent ceramics is a new group of advanced materials that are distinctively transparent with notable mechanical properties. These materials are not only visible to visible lights but also UV, infrared and radiofrequency. They are produced by very few countries and their supply is restricted because of their strategic applications.
Indian researchers developed transparent ceramics with the help of a technique called colloidal processing, which was followed by simultaneous application of temperature and pressure. This is the first such initiative in India. Previous attempts produced transparent ceramics at a laboratory scale or with low transparency. It can be used for thermal applications and personal protection systems.
