  • Method for producing synthetic quartz glass
    Patent number: 9481597
    Abstract: The invention relates to a method for producing synthetic quartz glass by vaporizing a polyalkylsiloxane as a liquid SiO2 feedstock (105), converting the vaporized SiO2 feedstock (107) into SiO2 particles, separating the SiO2 particles, forming a soot body (200) and vitrifying the soot body (200). According to the invention, the vaporizing of the heated SiO2 feedstock (105) comprises an injection phase in an expansion chamber (125), in which the SiO2 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.
