Based on the research in the medium and strong polar glass capillary column, the coating on the barium sulfate micro crystal modified surface with apolar and weak polar liquid phase is investigated.
In reaction process P-zeolite first appears the short columncrystal and then the crystal pattern changes from short column to rhombohedron with reaction time lasting.
在反应过程中,P沸石首先呈短柱状结晶,随着反应时间延长,结晶形态发生变化,由短柱状向菱面体过渡。
