The range of firing temperature of ceramic tube after dipping changed from 450 c to 1000 c . the above four slurries were also respectively favorable combination with al2o3 ceramic tube , and the range of firing temperature of ceramic tube after dipping slurry varied from 1 000 c to 1400 c 镀膜的陶瓷管烧成温度范围为450 1000 。前述的四种料浆也能良好地与al _ 2o _ 3陶瓷管结合，涂覆料浆的al _ 2o _ 3陶瓷管烧成温度为1000 1400 。
This paper mainly discusses the performance specification of plasma source ( gis ) , technology and quality of tio2 and sio2 coatings and the technology for large antireflection coatings deposited with plasma - iad . the research shows that the index of optical coating increases remarkably by using plasma ion assisted deposition and approach to the massive material further , the coating structure is more compacted than the one obtained through conventional deposition method and the adhesive power is high as well 研究了用于辅助镀膜的等离子体源( gis )的结构原理及性能指标，并从光学特性、显微特性和机械特性三方面着手，研究了使用等离子体源所做的单层tio _ 2膜和单层sio _ 2膜的成膜工艺与质量。
In this paper , the property difference of sio2 sols used for preparing thin films by esam method or sol - gel process has been discussed . three kinds of sio2 sols were prepared , catalyzed by hcl or nh3 h2o only , or hcl first and then nh3 h2o respectively ( please note : in following text , the sio2 sol catalyzed by hc1 first and then nh3 h2o and its correspondent films will be named sio2 sol 1 # and film 1 ; the sio2 sol catalyzed by nh3 h2o only and its correspondent films will be named sio2 sol 2 # and film 2 # ) . through investigating the assembling properties of the sols , observing thin films " microscopic structure with tem and testing their transmissivity with 721 spectrophotometer , we find that the first kind of sol is not suitable for preparing esam films , but the last two , i . e . sol 1 # and sol 2 # , are good 本文讨论了esam法制备薄膜所用的溶胶与sol - gel法所用的溶胶在性能上的区别，在hc1或nh _ ? h _ 2o分别单独催化和hc1 nh _ 3 ? h _ 2o分步催化三种催化条件下制备了sio _ 2溶胶(以下规定hc1 nh _ 3 ? h _ 2o分步催化的sio _ 2溶胶为1 ~ #溶胶，相应的薄膜为1 ~ #薄膜， nh _ 3 ? h _ 2o催化的sio _ 2溶胶为2 ~ #溶胶、相应的薄膜为2 ~ #薄膜) ，在通过组装薄膜并用透射电镜( tem )观察薄膜微观结构以及用721分光光度计测试样品的光透射率，得出了后两种催化方法所制备的溶胶适合于esam法镀膜，而第一种溶胶不适于用此法镀膜的结论，用傅立叶红外光谱( ft - ir )研究了溶胶组成；用差热失重分析仪( dta - tg )对胶体进行了热分析。
