Wollastonite mineral microwave dielectric ceramic material and preparation method thereof
The invention discloses a wollastonite mineral microwave dielectric ceramic material, which is prepared from the following components in percentage by mass: 61 to 65 percent of hexagonal crystal type CaSiO3, 33 to 35 percent of triclinic crystal type CaSiO3 and 2 to 4 percent of NaAlSi3O8. The invention also discloses a preparation method of the wollastonite mineral microwave dielectric ceramic material, which comprises the following steps: crushing and grinding wollastonite mineral powder, performing primary calcination, weighing the mineral powder after primary calcination, Na2CO3 and Al2O3 additives according to a ratio, performing primary wet ball milling, drying the powder after ball milling, performing secondary calcination, performing secondary wet ball milling on the powder after secondary calcination, and performing sintering to obtain the wollastonite mineral microwave dielectric ceramic material. And drying the powder after secondary ball milling to prepare a blank, and sintering to obtain the wollastonite mineral microwave dielectric ceramic material. The wollastonite mineral microwave dielectric ceramic material prepared by the invention has low relative dielectric constant and sintering temperature and excellent performance, and has huge application potential in the aspect of low-cost LTCC (Low Temperature Co-Fired Ceramic) microwave devices.
本发明公开了一种硅灰石矿质微波介质陶瓷材料，包括以下质量百分比组分：六方晶型CaSiO3占61％～65％，三斜晶型CaSiO3占33％～35％，NaAlSi3O8占2％～4％。本发明还公开了一种硅灰石矿质微波介质陶瓷材料的制备方法，硅灰石矿粉经破碎磨细后进行一次煅烧，一次煅烧后矿粉与Na2CO3、Al2O3添加剂按比例称取并进行一次湿法球磨，球磨后烘干粉体进行二次煅烧，二次煅烧后粉体进行二次湿法球磨，二次球磨后烘干粉末制备坯料后烧结获得硅灰石矿质微波介质陶瓷材料。本发明制备的硅灰石矿质微波介质陶瓷材料拥有低的相对介电常数和烧结温度，性能优异，在低成本LTCC微波器件方面有着巨大的应用潜力。
