Polycrystalline wafers of silicalite-1 etched by HF acid and viewed by SEM

HF etching of polycrystalline silicalite-1 wafers enables to visualize grain boundaries of non-calcined crystals by dissolution of a phase between individual crystals as well as to reveal resistant shells of calcined crystals by dissolution of a crystal bulk.
