Overview of usageof glass in medical practice such as surgery, diagnosis, therapy, dentistry and endoprosthetics. Types of glass which were reviewed: glass containers; optical, absorbent and liquid glass; glass fiber; X-ray and biological glass. A brief description of each material and the specifics of its use are provided also.

Optical glass is for making lenses and mirrors, which are mostly used in diagnostics, surgery and therapy.

Liquid phase technologies for high-grade ceramic oxide powders of technical purpose and methods of their modification have been developed. On the basis of physico-chemical research methods various mechanisms of modifying processes have been analyzed. Substitution of the main ions by doping ones occurs in complex oxide powders followed by the formation of solid solutions. A powder which was obtained via TiO2 modification by sulfur has a surface layer in which sulfur forms chemical bonds.
