LTCC powder with low dielectric constant and ultralow loss and preparation method thereof
The invention relates to LTCC (low temperature co-fired ceramic) powder with low dielectric constant and ultralow loss and a preparation method thereof, and belongs to the technical field of low temperature co-fired ceramics. The LTCC powder is prepared by taking a B2O3-SiO2-Al2O3 amorphous material and quartz glass powder as raw materials, the relative dielectric constant of the LTCC powder in a millimeter wave frequency band is about 3.9, the dielectric loss of the LTCC powder is about 7 * 10 <-4 > under 28GHz, the dielectric loss of the LTCC powder is about 8 * 10 <-4 > under 40GHz, the dielectric loss of the LTCC powder is about 1.4 * 10 <-3 > under 58GHz, and the LTCC powder shows the characteristics of low dielectric constant and ultralow loss in the millimeter wave frequency band; the amorphous material is prepared by adopting a sol-gel method, the treatment temperature is 1180 DEG C, the sintering method of the prepared LTCC powder is that the temperature is kept for 2 hours at 900 DEG C, and the raw materials do not contain heavy metals such as Pb, so that the production and post-treatment are more environment-friendly.
本发明涉及一种低介电常数超低损耗的LTCC粉体及其制备方法，属于低温共烧陶瓷技术领域。该种LTCC粉体由一种B2O3‑SiO2‑Al2O3无定形材料和石英玻璃粉为原料制成，其在毫米波频段的相对介电常数为3.9左右，在28GHz下为介电损耗约为7*10‑4，在40GHz下为介电损耗约为8*10‑4，在58GHz下为介电损耗约为1.4*10‑3，在毫米波频段表现出低介电常数和超低损耗的特性；无定形材料采用溶胶‑凝胶法制备，处理温度为1180℃，制备的LTCC粉体烧结方法为900℃下保温2h，且原料中不含Pb等重金属，生产以及后处理都更加环保。
