Embodiment 1
[0019] In a specific embodiment of the present invention, the mass percentage content of each oxide in the multi-component borosilicate glass is as follows:
[0020]
[0021] The preparation method of the low-temperature co-fired ceramic material in this embodiment comprises the following steps:
[0022] (1) Preparation of low-melting-point glass raw materials: weigh the corresponding amount of CaCO according to the mass percentage content of each oxide required for the above-mentioned low-melting-point glass phase 3 、BaCO 3 、H 3 BO 3 , SiO 2 , Li 2 CO 3 , ZnO, Al 2 o 3 ingredients, and mix well.
[0023] (2) Preparation of low-melting point glass: raise the high-temperature continuous glass melting furnace to 1450°C, then evenly add the above-mentioned mixed glass raw materials into the quartz crucible in the glass melting furnace, and use deionized water to accept the glass that flows out from the outlet of the quartz crucible. Glass melt to obtain glass frit. T...
