And then the effects of compositions on the mechanical performance, characteristic temperatures, thermal expansion and chemical stability of the glass were discussed. Researches on lead borate sealing glasses show that PbO/B2O3 ratio exerts the most important effect on glass network. ZnO is beneficial to stabilize the glass against devitrification . Bi2O3 has little effects on the sealing temperature, while it helps to adjust the thermal expansion coefficient of lead borate glasses in a definitive range. When 0.5～4 mol% GeO2 is introduced, the glass possesses the highest stability and lowest sealing temperature (400 ?C), which is desirable for low-temperature sealing.

通过对含铅的硼酸盐封接玻璃研究得出，PbO/B2O3比是影响玻璃网络最主要的因素；添加ZnO有助于增强玻璃的稳定性，抑制析晶；Bi2O3对高铅系列配方玻璃的封接温度影响不大，但可使铅硼系列玻璃体系的热膨胀系数在一定范围内可调；在高铅系列配方中，引入0.5～4mol%的GeO2可有效地抑制玻璃析晶，降低封接温度；最终获得了两种性能较好的低熔点铅硼酸盐封接玻璃配方，G3封接温度低达400℃，其PbO含量为54mol%左右，BL10玻璃的封接温度为440℃，但其铅含量大大降低，仅为36mol%。

It was found that increasing pressure for blank can improve the compactedness of blanks so as to make foam aluminium materials with homogeneous pores. Foaming temperature, as one of the main influencing factors on foaming process, should be controlled higher than the melting point of Al or Alalloy to a certain extant in order to keep a reasonable viscosity. Thus, the foam aluminum with homogeneous pores and high porosity is available. As shown by experiments, such materials should be made on conditions that they shall be protected with molten salt under 300?MPa pressure at 675～680?℃.
