    Abstract: An improved sol-gel process is disclosed for the making of large synthetic silica based bioactive materials objects crack-free. A series of ordered mesoporous SiO2—CaO—P2O5 sol-gel glasses which are highly bioactive are synthesized through a sol-gel process. The mesoporous glasses are highly bioactive compared with conventional ones, due to the increased textural characteristics, i.e. surface area. The bioactivity tests point out that the surface area, porosity, and 3D-structure become more important than chemical composition during the apatite crystallization stage in these materials, due to the very high textural parameters obtained. The product is intended to be used for tissue engineering applications.

    Abstract: A process for manufacturing glass bodies of doped silicate glass is disclosed. The process involves flame hydrolysis, wherein precursors for the forming of the doped glass are fed together with fuel gases into a single burner. A first formed body is generated on a target. The doped silicate glass produced in this way offers a low density of defects and a small breadth of striae. Preferably the first formed body is subsequently formed into a second formed body having a larger breadth and a smaller length than the first formed body. Thereby, the breadth of striae and the density of defects in the doped silica glass is further reduced.

    Abstract: The invention concerns a quartz glass body for an optical component for the transmission of UV radiation with a wavelength of 250 nm and less, especially for a wavelength of 157 nm, as well as a process for the manufacture of the quartz glass body where fine quartz glass particles are formed by flame hydrolysis of a silicon compound, deposited and vitrified. Suitability of a quartz glass as represented by high base transmission and radiation resistance depends on structural properties caused by local stoichiometric deviations, and on the chemical composition. The quartz glass body according to the inventions is distinguished by a uniform base transmission (relative change of base transmission ≦1%) in the wavelength range from 155 nm to 250 nm (radiation penetration depth of 10 mm) of at least 80%, a low OH content (less than 10 ppm by weight) and a glass structure substantially free from oxygen defect centers. A quartz glass body of this kind is manufactured by a process which allows bulk embedding of hydrogen or oxygen into the glass network in that at least a two stage heat treatment takes place at temperatures ranging from 850° C. to 1600° C. before the vitrification, the last stage comprising sintering at a temperature between 1300° C. and 1600° C. in an atmosphere containing hydrogen or oxygen, or a nonflammable mixture of these substances.
