This chapter focuses on inherent difficulties and procedures such as high-precision stoichiometry powder processing, green body formation and sintering in fabricating transparent ceramics. It explores some of the important applications of transparent ceramics in various fields. Polycrystalline ceramics can be said to be transparent when the incoming light leaves material without any losses such as absorption or scattering. Active transparent ceramics for applications, such as lasers or scintillators, need to satisfy a higher degree of optical quality compared to transparent windows. In addition to the precipitation technique, other solution-based processes have been used to synthesize ultra-fine powders for transparent ceramics. Most of the powder synthesis processes from the perspective of transparent ceramics use special additives, either organic or inorganic materials, to serve as dispersants, binders or sintering aids. Transparent ceramics have attracted tremendous attention among researchers and industries in a wide range of applications that require transparent materials with large dimensions along with properties similar to that of single crystals.
