    • The invention relates to a measurement method and device to be used in connection with a manufacturing process of a planar glass coating, in which manufacturing process for example a thermal reactor (10), such as a flame or plasma is used to produce aerosol particles (13) from reactants (12), which said aerosol particles (13) are guided on the surface of a substrate (14), thus forming a coating layer. According to the invention, the electric charge conveyed on the substrate (14) by the aerosol particles (13) entering the substrate is measured by means of a current measurement means (17) during the process to monitor the coating process. The current measurement means (17) is arranged to communicate with a process control unit (18) to adjust the process conditions according to predetermined threshold value. In an embodiment of the invention, the measurement is based on the electric charge attained intrinsically by the aerosol particles (13) during their formation. If necessary, it is also possible to use a separate charger (23), for example a so-called corona charger to charge the aerosol particles (13).

    • According to a known method for producing a SiO2 blank, SiO2 particles are formed in a plurality of deposition burners arranged in series, a burner flame being associated to each burner, and said particles are then deposited on a deposition surface of a carrier rotating about its longitudinal axis. The series of deposition burners moves back and forth according to a pre-determined displacement sequence along the blank being formed, and between inflection points at which the displacement direction is reversed. The burner flame forms a projection surface in a projection on a plane parallel to its main propagation direction, the lateral boundary lines of said projection surface forming an opening angle with the mean propagation direction. In order to provide a simple method for producing a porous blank, based on the above, and by which means a homogeneous quartz glass body is obtained, the opening angle ( alpha ) is set to a value of between 3 DEG and 15 DEG and the distance (D) between the deposition burner (2) and the deposition surface (10) is set between 170 mm and 240 mm.

    • In a furnace (10) for producing high purity fused silica glass boules, the refractory in the area of the burner holes reaches such elevated temperatures that cause impurities to leach out and the dissociation of the refractory, causing contamination of the silica glass. In order to reduce the temperature of the burner hole refractory, a porous insert or liner (16) having an outer housing portion (17) is positioned within the burner hole (14) in the furnace crown (12), and a suitable gas is supplied thereto. The insert has a closed-end flow passage (18) therewithin, having an inlet end (20) connected to a sources of gas under pressure. The gas diffuses through the porous liner and not only cools the liner and refractory, but also forms a boundary layer (22) along an inside surface (24) of the insert that prevents particle buildup. A burner (26) is sealed to the insert (16) with seals (28). The cooling of the insert and surrounding burner hole refractory prevents contamination of the silica glass from the refractory.
