Book Description
The problems involved in the preparation of single crystals of refractory insulating materials are briefly outlined. The current status of the preparation of insulating crystals by the electron beam heated floating-zone method is reviewed, and the disadvantages are noted. The conception, construction and test of a new electron beam optics are described, and the advantages are pointed out. Sapphire, ruby and tungsten rods were zoned in testing the new optics. The influence of zone length, liquid - solid interface geometry, foreheater and afterheater temperature, and mechanical translation and rotation systems on crystal perfection are discussed. (Author).
