WebDec 28, 2024 · For interstitial solid solutions, the impurity enters the interstices of the crystal lattice, further disrupting the crystal order. 43 True solid solutions are energetically unfavourable, and thus they are not expected to occur as a main mechanism in kinetic-driven processes. WebIn general, analytical reagent-grade chemicals are of high purity, and yet few of them are better than 99.9% pure. This means that a foreign atom or molecule is present for every 1000 host atoms or molecules in the crystal. Perhaps the most demanding of purity is in the electronic industry.
