Embodiment 1
[0033] A high temperature and high pressure resistant glass material for sealing, made of the following components by weight: SiO 2 : 0.9kg; H 3 BO 3 : 2.5kg; Al 2 o 3 : 0.4㎏; SrCO 3 : 0.5kg; Pb 3 o 4 : 5㎏; and other impurity components that are inevitably brought in ≤0.1㎏.
[0034] The preparation method of the above-mentioned high temperature and high pressure resistant glass material for sealing comprises the following steps:
[0035] a), batching: take each component according to parts by weight;
[0036] b), ball milling: put each component prepared in step a into the ball mill and carry out mixing and ball milling for 60 minutes at a speed of about 350r / min, so that the ingredients are evenly mixed;
[0037] c), pre-sintering: take out the ball-milled material in step b and place it in a crucible, put it into a sintering furnace, and raise the temperature up to 800°C at a rate of about 5°C / min in an air atmosphere for pre-sintering, pre-sintering The time is 30 ...
Embodiment 2
[0050] A high temperature and high pressure resistant glass material for sealing, made of the following components by weight: SiO 2 : 1.2kg; H 3 BO 3 : 2.7㎏; Al 2 o 3 : 0.6kg; SrCO 3 : 0.8㎏; Pb 3 o 4 : 5.3㎏; and make other impurity elements ≤ 0.1㎏.
