High-strength ceramic dielectric material and preparation method thereof
The invention relates to the field of ceramic dielectric materials, in particular to a high-strength ceramic dielectric material and a preparation method thereof. The Nd2O3 glass powder is prepared from the following components in percentage by mass: 5 to 25 percent of Nd2O3 and 75 to 95 percent of 0.5 Ag2O to 45K2O to 50Bi2O3 glass powder. According to the invention, a 0.5 Ag2O-45K2O-50Bi2O3 system is selected, the glass ceramic is prepared by using a powder process, and Nd2O3 is added as a nucleating agent, so that the crystal lattice energy of the system can be activated, and the crystallization is uniform, so that the high-strength glass ceramic has the advantages of low dielectric constant, low dielectric loss, high stability, no lead and environmental protection while meeting the high strength.
本发明涉及陶瓷介质材料领域，具体是一种高强度陶瓷介质材料及其制备方法。是由质量百分比为5‑25％的Nd2O3和75‑95％的0.5Ag2O‑45K2O‑50Bi2O3玻璃粉组成的。本发明选择0.5Ag2O‑45K2O‑50Bi2O3系统，利用粉末法工艺制备玻璃陶瓷，添加Nd2O3为晶核剂的方法，可以活化系统的晶格能，使其析晶均匀，从而满足高强度的同时，具有介电常数低、介电损耗低、稳定性高、无铅环保的优势。
