Float zone method

The vertical method shown above has sometimes been called the "floating zone" method. The thickness of polycrystalline rod determines the...

Single crystals of WC were grown by two methods the flux method and the floating zone method. In the flux method, a mixture of 14 mol%WC and... 

Boride crystals can also, of course, be obtained by other methods, for example, by preparing feed rods, using methods (1) and (2) above, for the floating zone method to grow crystals. 

Single crystals of cobaltites Lao.xCao CoCL were grown using the floating zone method with radiation heating. The X-ray diffraction analysis at 296 K confirmed that the samples were of single phase with a... 

The substituted garnet plates can be produced by slicing from a single crystal rod grown by the floating zone method or, more economically, from thick films grown onto a host substrate by liquid phase epitaxy (see Section 3.11). The plates are lapped, polished, coated with antireflection layers and then diced to produce the final elements ( 2mm side by 100/mi thickness) ready for assembly into the isolator.

The room-temperature elastic constants of single crystals with the stoichiometry B5 fiC synthesized by the optical floating zone method have been measured using a resonant ultrasound spectroscopy technique [531]. The single crystal elastic constants indicate the strong anisotropy of the structure Cn = 542.81, Cg3 = 534.54, Ci3 = 63.51, C12 = 130.59, and 44= 164.79GPa, respectively.
