目前国内生产钼板、钼棒、钼顶头等制品均采用中颗粒、细颗粒钼粉。近年来天津大学冶金分校报导了采用0.3μm超细钼粉生产0.2mm厚的钼薄板,具有节电、节水等优点。本文对钼粉粒度大小与烧结坯晶粒度的关系进行了讨论。在相同的压型与烧... 目前国内生产钼板、钼棒、钼顶头等制品均采用中颗粒、细颗粒钼粉。近年来天津大学冶金分校报导了采用0.3μm超细钼粉生产0.2mm厚的钼薄板,具有节电、节水等优点。本文对钼粉粒度大小与烧结坯晶粒度的关系进行了讨论。在相同的压型与烧结条件下,超细颗粒钼粉晶粒长大速度比中颗粒钼粉、细颗粒钼粉快得多。 展开更多

Glasses based on ZnO-Bi_2O_3-B_2O_3 system are expected to be a new kind of sealing glasses because of their low melting temperature and other properties.In order to reveal the effect of B_2O_3 on the rheological behavior of ZnO-Bi_2O_3-B_2O_3 system glass melt,the properties of viscosity,thermal expansion,fluxion property and wetting process between cylinder samples and stainless steel were investigated with the rotating crucible viscometer,dilato meter and high-temperature microscope.The structure of sintered glass samples was investigated with scanning electron microscope.The results show that the B_2O_3 content increasing in B_1-B_3 at the given temperature between 400 ℃ and 500 ℃ leads to the increasing of the sample viscosity.When the amount of B_2O_3 increases from 5.24%to 9.24%(mass fraction),the coefficients of thermal expansion of glass samples decrease smoothly from 10.94×10^(-6) to10.71×10^(-6) and 10.38×10^(-6) ℃^(-1) respectively.In the case of sealing temperature,its value increases from 453 ℃ to 494 ℃.ZnO-Bi_2O_3-B_2O_3 system low-melting glass powder sintering was with viscous liquid to participate,which could make the densification of glass sample more effective and more efficient.With the content of B_2O_3 increasing,the wetting angle between the glasses samples and stainless steel could also increase,and the resulting appropriate sealing temperature range is 460-490 ℃. 展开更多
