应用大功率CO_2激光器非平衡态高温、快速合成陶瓷新工艺,合成了Al_2O_3-WO_3系线性NTC热敏材料。并从激光合成工艺、材料组成、热老化、材料的抗氧化性及耐酸碱性等方面对合成陶瓷材料进行了试验。
A new type of Al 2 O 3 -WO 3 linear NTC thermosensitive material was synthesized by non-equilibrium high-temperature and high-speed synthesis of high-power CO 2 laser. The synthetic ceramic materials were tested from the aspects of laser synthesis, material composition, heat aging, oxidation resistance and acid and alkali resistance of the materials.
