Ce—TZP陶瓷人工关节材料的研究

研究了用做人工关节材料的一种ＺｒＯ２增韧陶瓷Ｃｅ－ＴＺＰ陶瓷，藉以进一步研制性能优于其它陶瓷的人工关节，用ＸＲＤ，ＯＭ分析了材料的矿物组成和微观结构，测定了材料的性能，结果表明，在１６５０℃烧成的１２ｍｏｌ％Ｃｅ－ＴＺＰ陶瓷材料性能最佳；断裂韧性为１１．１１８０ＭＰａ．ｍ＾１／２抗弯强度为５１２．９５ＭＰａ，初步探讨了材料的成分，烧成温度，微观结构与性能的关系，本文还研究了用于Ｃｅ－ＴＺＰ陶瓷人工     

STUDY ON PREPARATION OF YBa_2Cu_3O_(7-x) ULTRAFINE POWDERS BY SOL-GEL PROCESS

The ultrafine powders of YBa_2Cu_3O_(7-x) withthe size of 100nm were synthesized by Sol-Gel process using cit-rate as complex and ammonium hydroxide to adjust pH of solu-tion. The process of Sol formation and Gel polymerization ofYBa_2Cu_3O_(7-x) in the Sol-Gel synthetic reaction has bee studied.The particle size,pruity,sintering activity and superconductingproperties of YBa_2Cu_3O_(7-x)prepared by Sol-Gel method are betterthan by solid state reaction.

纯刚玉代铂坩锅的研制

本文研究了用作铂金坩蜗代用品的纯刚玉坩埚。分析了纯刚玉的结构，测试了纯刚玉坩埚的性能，并对影响纯刚玉坩埚性能的因素进行了探讨。     

ON HIGH-POROUS CERAMIC FOR PHARMACEUTICAL CARRIER

A kind of hydroxyapatite (HA) high-porous ceramic (HPC) which is used as pharmaceutical carrier for spinal tuberculosis treating is investigated. the structure of HPC is analyzed and physicochemical properties are determined. Experiments and clinical application show that when HPC carrying antituberculosis drug was imbedded in the tuberculosis focus-the drug in effective concentration can continuously be released for 27 weeks-also-the drug concentration achieves high local level but low systematic level -thus the curative effect can distinctly enhanced.
