  • Publication number: 20250128977
    Abstract: One aspect is a heat reflective member, a laminated structure in which quartz glass layers are formed on an upper surface and a lower surface of a siliceous sintered powder layer. The heat reflective member has an impermeable layer formed at a portion of the siliceous sintered powder layer at a cut-out end portion of the heat reflective member. The impermeable layer has a thickness at least larger than half of a thickness of the siliceous sintered powder layer and through which a gas or a liquid is prevented from penetrating. A buffer layer is formed between the impermeable layer and the siliceous sintered powder layer next to the impermeable layer and spaced apart from the cut-out end portion. The buffer layer changes in density from the impermeable layer toward the siliceous sintered powder layer.

  • Patent number: 12221345
    Abstract: Known processes for preparing a porous carbonaceous material require lengthy polymerization and washing steps involving solvents or neutralizing agents. The use of high quantities of pore formers leads to a lower carbon yield and higher costs, and use of sulphuric acid leads to sulphur contamination of the final material, but also to corrosion and corrosive by-products and a more complicated handling of the process. In order allows the manufacturing of a porous carbonaceous material with a high pore volume and avoiding the disadvantages of the known methods, a process is provide that comprise the steps of a) providing at least one carbon source and at least one amphiphilic species, b) combining at least the carbon source and the amphiphilic species to obtain a precursor material, c) heating the precursor material to a temperature in the range between 300° C. and 600° C.

  • Patent number: 12180106
    Abstract: To achieve a high degree of precision and an exact positioning of anti-resonant elements in a sufficiently stable and reproducible manner in an anti-resonant hollow-core fiber which has a hollow core extending along a fiber longitudinal axis and an inner jacket region that surrounds the hollow core, formation of anti-resonant element precursors includes formation of elongated pressure chambers, each of which adjoins a wall deformable under pressure and heat in the region of target positions of the anti-resonant elements. A section of the deformable wall is caused to protrude in the direction of a cladding tube inner bore, thereby forming an anti-resonant element or a precursor for same, while carrying out a process of elongating a primary preform to form the hollow-core fiber or further processing the primary preform to a secondary preform from which the hollow-core fiber is drawn.
