    摘要： A process for manufacture of a component made of opaque synthetic quartz glass, and a quartz glass tube manufactured according to said process. The process comprises (i) providing a starting material in the form of granulated material of highly pure, synthetic SiO2 comprising at least partially porous agglomerates of SiO2 primary particles, the granulated material having a compacted bulk density of no less than 0.8 g/cm3, (ii) filling the granulated material into a mold and converting it to an opaque quartz glass preform through a process of melting, and (iii) reshaping the preform in a heat reshaping process to obtain a component made of opaque quartz glass. A quartz glass tube is made of quartz glass consisting of a granulated material of synthetic SiO2 with a lithium content of no more than 100 wt-ppb, and the wall thickness of said component being in the range of 0.5 mm to 15 mm.

    摘要： A quartz glass crucible for pulling a single crystal, which comprises a cylindrical straight portion, a bottom portion and a curved intermediate portion for connecting the straight portion and the bottom portion. The straight portion has an opaque area positioned within about 75% or less of the total height of the crucible, measured from the upper open end of the crucible. The opaque area in the straight portion has a total bubble volume which ranges from about 7.times.10.sup.-3 cm.sup.3 /cm.sup.3 to 30.times.10.sup.-3 cm.sup.3 /cm.sup.3. The remaining straight portion, the curved intermediate portion and the bottom portion consist of two layers. One layer is an inner transparent layer having a total volume of bubbles of about 4.times.10.sup.-3 cm.sup.3 /cm.sup.3 or less and corresponds to from about 20% to 60% of the thickness of the crucible, measured from the inside surface thereof. The other layer is an outer opaque layer having a total volume of bubbles ranging between about 7.times.10.sup.-3 cm.sup.3 /cm.sup.3 and 30.times.10.sup.-3 cm.sup.3 /cm.sup.3, which is integral with the opaque area of the upper part of the straight portion.

    摘要： A method of producing a substrate having a frosted appearance, an article having a frosted appearance and frost-imparting compositions are disclosed. The method includes applying a frost-imparting composition onto a ceramic substrate and firing the coated substrate above 400° C. to impart the frost appearance. The frost-imparting composition comprises a liquid vehicle, 20% to 90% by weight of glass frit particles and less than 10% by weight of at least one gas-releasing material, inactive below an activation temperature of at least 400° C. The gas releasing material may include carbonate, nitrate, iodate, bromate, chlorate, fluoride, manganate, dimanganate and sulfate compounds. The firing temperature is chosen to be above the activation temperature of the gas-releasing material, above which the gas-releasing material yields gas bubbles and above a temperature that causes the glass frit particles to behave as a viscous liquid.
