Component for optical glass manufacturing device
A member for an optical glass manufacturing device, which is exposed to a gas containing a halogen element in a high-temperature environment of 1100 DEG C or more, and which is mainly composed of a dense ceramic that is silicon nitride, and has a surface layer having a porosity lower than an internal porosity.
光学玻璃制造装置用构件，在1100℃以上的高温环境下暴露于包括卤素元素的气体中，主要成分由致密质陶瓷构成，所述致密质陶瓷是氮化硅，表层的气孔率比内部的气孔率小。
