Aluminum oxide ceramic production process
The invention relates to an aluminum oxide ceramic production process. The process comprises the following steps: ceramic pretreatment: cleaning the surface of a to-be-metalized area of ceramic; slurry treatment: mixing molybdenum powder, aluminum oxide and silicon dioxide according to a certain proportion to obtain molybdenum slurry, placing the molybdenum slurry in a binder, and fully and evenlystirring; silk-screen printing: uniformly coating the upper and lower silk-screen printing surfaces of the ceramic with the molybdenum slurry; metalized sintering: forming a metalized layer on the surface of the ceramic to prepare metalized ceramic; and hot-pressing sealing: sealing the metallized ceramic, an inner nickel ring and an outer nickel ring. The metallized ceramic prepared by the aluminum oxide ceramic production process disclosed by the invention can stably operate for a long time in a high-temperature molten salt corrosion environment of 270-350 DEG C, is suitable for a sodium salt battery, and meets the working and using requirements of a sodium salt battery.
本发明涉及一种氧化铝陶瓷生产工艺，包括下列步骤：陶瓷预处理：陶瓷待金属化区域表面清洁处理；浆料处理：将包括钼粉、氧化铝和二氧化硅按照一定比例进行混合得到钼浆料，并置于粘结剂中进行充分搅拌均匀；丝网印刷：将钼浆料均匀涂覆在陶瓷上下丝印表面；金属化烧结：在陶瓷表面形成金属化层，制成金属化陶瓷；热压封接：将金属化陶瓷和内外镍环进行封接。本发明的氧化铝陶瓷生产工艺制得的金属化陶瓷能够在270～350℃高温熔盐腐蚀环境中长期稳定运行，适用于钠盐电池，满足钠盐电池工作使用要求。
