Patent number: 9926205Abstract: A method for producing antimony trisulfide can inexpensively produce antimony trisulfide that has a relatively low content of lead, arsenic, and crystalline silica (i.e., impurities). The method includes charging a reaction vessel with an antimony trioxide powder and sulfur, and heating the inside of the reaction vessel to react antimony trioxide with sulfur. Since antimony trioxide is obtained by volatilization-oxidation refining, antimony trioxide has a small particle size and a large specific surface area, and exhibits good reactivity, and high-purity antimony trioxide having a low content of impurities (e.g., lead, arsenic, and crystalline silica) is easily available. It is possible to inexpensively produce antimony trisulfide having a low content of impurities by utilizing high-purity antimony trioxide as a raw material.Type: GrantFiled: October 2, 2012Date of Patent: March 27, 2018Assignee: Nihon Seiko Co., Ltd.Inventors: Satoshi Kitazono, Shota Ishida

Patent number: 8575838Abstract: A ceramic burner, a ceramic metal halide lamp, and a method of sealing the ceramic burner is provided. The ceramic burner comprises a discharge vessel enclosing a discharge space that is provided with an ionizable filling comprising one or more halides. The discharge vessel comprises a ceramic wall arranged between a first and a second end portion. The first and the second end portion are arranged such that current supply conductors are passed through the end portions to respective electrodes arranged in the discharge space for maintaining a discharge. The ceramic wall of the discharge vessel comprises a tube for introducing the ionizable filling into the discharge vessel during manufacture of the ceramic burner.
