JSQでは、最高品質の石英原料粉を使い、また必要に応じて独自の高純度化技術を駆使して、高純度石英粉を安定的に確保しています。そしてクリーンな環境に設置されたルツボ溶融炉、加工設備で、石英ルツボを製造しています。
できあがった石英ルツボは、クリーンルーム内で全数、外観、寸法、内面の汚れ、気泡などを厳密に検査し、合格したルツボだけを洗浄、シール、包装し、データシートを添付して出荷します。
Employing advanced technology to create high-purity quartz crucibles
JSQ uses quartz powder of the highest quality, and employs exceptional purification technology of its own to maintain a stable supply of high-purity quartz powder.
The quartz crucibles are produced in the manufacturing furnaces placed in a clean environment.
All the quarts crucible produced are rigorously inspected to ensure the conformance to the highest standards for exterior appearances, dimensions, contaminants on inner surfaces, and to make sure that there are no bubbles. Only those crucibles that pass this inspection are sealed in the clean room, affixed with data sheets, and shipped to each destination.

JSQの石英ルツボは、気泡をほとんど含まない内面透明層と微気泡を多く含む外面気泡層の二重構造を持ち、シリコン単結晶の引き上げ性能向上に役立っています。また、超高純度の合成石英原料を内面層に使用した二層構造石英ルツボも合成石英ルツボとして製品化しています。
Quality creating the ultimate in technology
JSQ's quartz crucibles are manufactured with a double structure comprised of an inner transparent layer with very few bubbles and an outer bubble layer with many micro bubbles which help improve the pulling performance of single crystal silicon. Further, quartz crucibles with a two-layered structure using synthetic quartz powder of exceptional purity for the inner layer are commercialized as synthetic quartz crucibles.
