Diffusion crystallization technique dilution

The monoclinic form ( 3-lead azide) was first grown by Miles by a diffusion technique [18]. Dilute solutions of a lead salt and sodium azide were allowed to diffuse together in a water medium to cause crystallization. Numerous spontaneous explosions occurred using this method however, the crystals, once... 

Diffuse Reflectance-. Diffuse reflectance, or diffuse reflectance infrared Fourier transform spectrometry (DRIFTS), exploits surface interactions and reflection. Although samples still are mixed with KBr, there is no need to press the mixture into a clear pellet. The technique is also more sensitive than traditional dispersive IR and requires less material than a pellet. The sample is mixed with KBr to create a dilute solid solution of reasonably uniform small crystal size. The mixture is placed in a small cup, and the IR beam is directed onto the surface, where...
