Abstract: A fused quartz article, such as a muffle tube or crucible, with enhanced creep resistance. The enhanced creep resistance is the result of controlled devitrification of the fused quartz article. Controlled devitrification is achieved by coating the article with a colloidal silica slurry doped with metal cations, such as barium, strontium, and calcium. The metal cations in the slurry promote nucleation and growth of cristobalite crystals into the fused quartz at temperatures in the range from about 1000° C. to about 1600° C. The cristobalite has significantly higher viscosity, and therefore greater creep resistance at elevated temperatures, than fused quartz. Methods for applying a doped coating to a fused quartz article and improving the creep resistance of a fused quartz article are also disclosed.

Abstract: The high refractive dielectric film which can be used stably as a constituent material of an optical multi-layer film, namely, and which does not cause change over time in optical properties and has small film stress, is an amorphous material having no columnar structure, obtained by adding to a main component titanium oxide (TiOx: 1?x?2) another metal oxide (MOw: M represents a metal such as niobium, tantalum, 1?w). Though titanium oxide is a material which tends to manifest a crystalline structure even in the form of a thin film, a mixed high refractive dielectric film can be obtained, containing titanium oxide causing little change over time in optical properties by rendering the resulting thin film amorphous by inhibiting growth of a crystal of titanium oxide by adding another metal oxide.

To produce the subject of the invention the substrate is coated with a composition containing a glass flux and structure-forming particles, and the layer is burnt in and made hydrophobic.
