Embodiment 1
[0027] The preparation method of this thick-film dielectric glass powder is carried out according to the following steps:
[0028] The first step is to select raw materials, and the raw materials are selected according to the following components and parts by weight: 20 parts of pyrophyllite, 30 parts of limestone, 1 part of boric acid, 3 parts of titanium dioxide, 3 parts of zirconium dioxide, 2 parts of cobalt trioxide, industrial oxidation Aluminum 5 parts;
[0029] The second step is mixing and preheating. The raw materials selected in the first step are fully mixed and put into a planetary ball mill for ball milling. When the mixed raw materials are in a fine powder state, take them out and put them in a graphite crucible, and then put the graphite crucible into the working Preheat in a muffle furnace with a temperature of 230°C for 40 minutes. After the preheating is complete, put the raw material mixture into a high-temperature resistance furnace. The high-temperature r...
Embodiment 2
[0037] The preparation method of this thick-film dielectric glass powder is carried out according to the following steps:
[0038] The first step is to select raw materials, and the raw materials are selected according to the following components and weight percentages: 25 parts of pyrophyllite, 40 parts of limestone, 2 parts of boric acid, 3 parts of titanium dioxide, 3 parts of zirconium dioxide, 1 part of cobalt trioxide, industrial 6 parts of aluminum oxide;
[0039] The second step is mixing and preheating. The raw materials selected in the first step are fully mixed and put into a planetary ball mill for ball milling. When the mixed raw materials are in a fine powder state, take them out and put them in a graphite crucible, and then put the graphite crucible into the working Preheat in a muffle furnace with a temperature of 260°C for 40 minutes. After the preheating is completed, put the raw material mixture into a high-temperature resistance furnace. The high-temperatur...
