AGG3979, Potassium Chloride Crystals 10x10x10mm (Pack of 5)

High purity optical grade single crystals of sodium chloride, potassium bromide and potassium chloride are excellent substrates for growing epitaxial films. These crystals are ideal for thin film research and are excellent substrates on which to evaporate metals. For most applications it is advisable to use only freshly cleaved substrates. Pieces of 1 - 2 mm thickness can be cleaved to be used as substrates. The cleaved surfaces produce atomically flat areas however cleavage steps over different atomic planes should be expected. The material is supplied as 10 mm square crystals of (100) orientation
