Embodiment 1
[0058] A preparation method of titanium and titanium alloy and Kovar alloy sealing glass material for thermal battery, specifically comprising the following steps:
[0059] 1), select chemical composition batching by following weight percentage:
[0060] SiO 2 15%, B 2 o 3 35%, Bi 2 o 3 5%, Al 2 o 3 17.5%, Na 2 O is 2.4%, K 2 O is 2.5%, MgO is 2.5%, CaO is 5%, SrO is 5%, ZnO is 10%, TiO 2 0.05% for CoO and 0.05% for CoO;
[0061] 2) Put the raw materials of the above-mentioned components in a ball mill for ball milling, so that the ingredients are mixed evenly, the grinding speed is 300r / min, and the time is 30min;
[0062] 3) Put the ball-milled and mixed materials in step (2) in a corundum crucible or a platinum crucible, place the crucible in a high-temperature lifting furnace, and raise the temperature to 700°C at a heating rate of 10°C / min in an air atmosphere and keep it warm for 40min. Then increase the temperature at a rate of 10°C / min to 1350°C and keep it ...
