    Abstract: A process for making cerium dioxide nanoparticles containing at least one transition metal (M) utilizes a suspension of cerium hydroxide nanoparticles prepared by mechanical shearing of an aqueous mixture containing an oxidant in an amount effective to enable oxidation of cerous ion to ceric ion, thereby forming a product stream that contains transition metal-containing cerium dioxide nanoparticles, Ce1-xMxO2, wherein “x” has a value from about 0.3 to about 0.8. The nanoparticles thus obtained have a cubic fluorite structure, a mean hydrodynamic diameter in the range of about 1 nm to about 10 nm, and a geometric diameter of less than about 4 nm. The transition metal-containing crystalline cerium dioxide nanoparticles can be used to prepare a dispersion of the particles in a nonpolar medium.

    Abstract: Cylindrical optical components of quartz glass are known, which have an inner zone made of an inner zone glass, which extends in the direction of the longitudinal axis and is surrounded by a jacket zone made of a jacket zone glass, the average pt wall thickness thereof varying at least over a part of its length in the direction of the longitudinal axis of the component. The aim of the invention is to provide a method that allows a simple and cost-effective production of such an optical component from quartz glass. A method is proposed according to the invention, comprising the following method steps: (a) providing a first parison made of an inner zone glass, which has a first contact surface on the end face, said contact surface having a conical external contour; (b) providing a second parison from the jacket zone glass; (c) embedding the contact surface with a conical external contour into the jacket zone glass and welding the contact surface to the jacket zone glass, thereby forming a composite parison which has a cone-shaped inner zone area of inner zone glass in a contact area, said inner zone area being surrounded by a jacket zone having the shape of an inner cone; and (d) elongation of the composite parison to form the optical component or a preproduct of the component.

    Abstract: The aim of the invention is to improve a generally known method for producing quartz glass doped with fluorine, wherein SiO2 particles are formed in the presence of fluorine by means of a plasma deposition process, deposited in layers on an outer envelope of a cylindrical quartz glass substrate body rotating about its longitudinal axis, and vitrified to form a layer of quartz glass with a fluorine content of at least 1.5 wt. %, in such a way that a quartz glass semifinished product with a high fluorine content, characterised by a high basic transmission in the UV wavelength range, is obtained. To this end, the substrate body has at least one reservoir layer of quartz glass at least in the region of the outer envelope thereof, having a minimum hydroxyl group content of 200 wt. ppm and/or a minimum hydrogen content of 1×1017 molecules/cm3, and the substrate body is either fully or partially removed following the deposition of the quartz glass layer doped with fluorine.
