High-curie-point low-temperature co-fired piezoelectric ceramic material and preparation method thereof
The invention relates to the technical field of low-temperature co-fired ceramic materials, in particular to a high-curie-point low-temperature co-fired piezoelectric ceramic material and a preparation method thereof.The high-curie-point low-temperature co-fired piezoelectric ceramic material comprises, by weight, 97.4%-99.2% of barium titanate, 0%-1% of calcium borosilicate glass, 0%-1% of barium titanate, 0%-1% of barium titanate, 0%-1% of barium titanate, 0%-1% of barium titanate, 0%-1% of barium titanate, 0%-1% of barium titanate, 0 0.5%-2.5% of copper oxide and 0.05%-2% of vanadium pentoxide. The invention provides the high-curie-point low-temperature co-fired ceramic material, the low-temperature co-fired ceramic material is low in sintering temperature, short in sintering time and excellent in matching performance with noble metals, so that the content of high-temperature-resistant noble metals such as platinum and palladium in the LTCC material can be reduced, co-firing can be realized by selecting common conductive materials such as silver, the manufacturing cost is greatly reduced, and the low-temperature co-fired ceramic material is suitable for industrial production. And meanwhile, the LTCC material prepared by the preparation method has a relatively high Curie temperature, so that the LTCC material has a relatively wide application temperature range and is suitable for more application environments, and the production cost of LTCC is greatly reduced.
本发明涉及低温共烧陶瓷材料技术领域，尤其涉及一种高居里点低温共烧压电陶瓷材料及其制备方法，一种高居里点低温共烧压电陶瓷材料及其制备方法，包括如下按照重量份数计的组分：97.4％－99.2％的钛酸钡，0％－1％的钙硼硅玻璃，0.5％－2.5％的氧化铜和0.05％－2％的五氧化二钒。本发明提供了一种高居里点低温共烧陶瓷材料，该低温共烧陶瓷材料烧结温度低，烧结时间短，与贵金属匹配性能优良，从而可以降低LTCC材料中铂、钯等耐高温贵金属的含量，选用银等普通导电材料即可实现共烧，大大降低了制造成本，同时该制备方法制备得到的LTCC材料具有较高的居里温度，使其具有较宽的应用温度范围，适用更多的应用环境，大大降低了LTCC的生产成本。
