WebJul 4, 2024 · An edge dislocation in a crystal causes the planes of atoms in the lattice to deform where the extra plane of atoms begins (Figure 12.4. 2 ). The edge dislocation frequently determines whether the entire solid will deform and fail under stress. Figure 12.4. 2: Edge Dislocations. WebThere are two key methods used to obtain oxygen gas. The first is by the distillation of liquid air. The second is to pass clean, dry air through a zeolite that absorbs nitrogen and leaves oxygen. A newer method, which gives oxygen of a higher purity, is to pass air over a partially permeable ceramic membrane.
