    摘要： The invention starts from a method for producing a crucible of quartz glass in that SiO
    2 inner layer granules are vitrified in a rotating melting mold (1), which is covered at least in part by a heat shield (2), in a light gas-containing atmosphere under the action of a plasma to obtain a transparent inner layer, at least part of the light gas being supplied to the melting mold (1) through a gas inlet (8,9) of the heat shield. In order to form an inner layer with a particularly low bubble content and with minimal efforts in terms of energy and material, it is proposed that in a layer-forming step preceding the vitrifying step, a granule layer (14) of the SiO
    2 inner layer granules is formed on the inner wall, and wherein the plasma zone (13) and the heat shield (2) together with the gas inlet (8,9) are movable at least in a direction perpendicular to the rotation axis and are moved laterally in the direction of the granule layer (14) during the vitrifying step so as to vitrify the granule layer (14).

    摘要： The invention relates to a method for producing synthetic quartz glass by vaporizing a polyalkylsiloxane as a liquid SiO
    2 feedstock (105), converting the vaporized SiO
    2 feedstock (107) into SiO
    2 particles, separating the SiO
    2 particles, forming a soot body (200) and vitrifying the soot body (200). According to the invention, the vaporizing of the heated SiO
    2 feedstock (105) comprises an injection phase in an expansion chamber (125), in which the
    SiO
    2 feedstock (105) is atomized into fine droplets, wherein the droplets have an average diameter of less than 5 pm, and wherein the atomizing of the droplets takes place in a preheated carrier gas stream which has a temperature of more than 180°C.

    摘要： A known quartz glass crucible for crystal pulling consists of a crucible wall, having an outer layer which is provided in an external area thereof with a crystallisation promoter which results in crystallisation of quartz glass, forming cristobalite when the quartz glass crucible is heated according to specified use in crystal pulling. The aim of the invention is to provide a quartz glass crucible which has a long service life. As a result, the crystallisation promoter contains, in addition to a silicon, a first component which acts as a reticulating agent in quartz glass and a second component which is free of alkali metals and which acts as an agent forming separating points in quartz glass. The above mentioned components are contained and incorporated into a doping area (8) of the outer layer (6) having a layer thickness of more than 0.2mm.
