Title:
LOW TEMPERATURE CO-FIRED CERAMIC MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/040749
Kind Code:
A1
Abstract:
A low temperature co-fired ceramic material and a preparation method therefor. The low temperature co-fired ceramic material consists of CaO, B2O3, SiO2, nano Al2O3, MgO, and nano ZrO2. The mass percentages of the components are: CaO: 35%-50%; B2O3: 5%-15%; SiO2: 40%-55%; nano Al2O3: 1%-5%; MgO: 1%-5%; and nano ZrO2: 1%-5%. The preparation method comprises: performing ball mill mixing according to the formula, and then performing high temperature sintering; quenching in deionized water, grinding, performing wet ball milling, drying and grinding; and finally, granulating to prepare a green body, then debinding and sintering to obtain the low temperature co-fired ceramic material. The low temperature co-fired ceramic material has low dielectric constant, low loss (less than 100 GHz), and good overall performance.
