    摘要： To provide granules for the production of silicate glass, said granules being less likely to adhere even if heated at a high temperature exceeding 800°C. A method for producing granules, which has a step of mixing a glass raw material composition composed essentially of an alkali metal source, an alkaline earth metal source and a powdery silicon source, with water, followed by compression molding, and which is characterized in that the glass raw material composition contains at least 50 mass% of the silicon source, and at least 10 mass% in total of the alkali metal source and the alkaline earth metal source, as calculated as oxides, based on 100 mass% of the silicate glass obtainable from the granules, the alkali metal source contains an alkali metal carbonate, and D90 representing the particle size at a cumulative volume of 90% in the particle size accumulation curve of the alkaline earth metal source is at most 100µm.

    摘要： The present invention provides a method for producing a silica container, a method for producing a silica container arranged with a silica substrate having a rotational symmetry, wherein the method comprises a step of forming a preliminarily molded silica substrate to an intended shape by feeding a powdered substrate's raw material (silica particles) to an inner wall of a carbon-made outer frame having aspiration holes with rotating the outer frame, and a step of forming the silica substrate wherein the preliminarily molded substrate is degassed by aspiration from its outer peripheral side with charging from an inner peripheral side of the preliminarily molded silica substrate a reducing gas containing more than 10% by volume of an H 2 gas, and at the same time heated from inside the preliminarily molded silica substrate by a discharge-heat melting method with carbon electrodes, thereby making an outer peripheral part of the preliminarily molded silica substrate to a sintered body while an inner peripheral part of the preliminarily molded silica substrate to a fused glass body. With this, provided are a method for producing a silica container having a high dimensional precision and a high thermal distortion resistance in a low production cost by using powders mainly comprised of a silica as a main raw material, as well as a silica container thereof.
