发明名称 NUCLEOUS BODIES FOR THE SYNTHESIS OF QUARTZ CRYSTALS ORIENTATED BY ST-SECTION AND AT-SECTION AND METHOD FOR THEIR PREPARATION
摘要 The quartz nucleous bodies (18, 40) with ST section and AT section are used for the synthesis of quartz crystals. By the method, an elongated quartz nucleus body (18) at an angle of about 42.75 deg. at revolutions around axis X (20) from axis +Z (22) to axis -Y (24), defining the ST section, and quartz cystal rod (32) produced by it are produced. BY the method, an elongated quartz nucleus body (40) at an angle of about 35.25 deg. in revolutions around axis X (20) from axis +Z (22) to axis -Y (24), defining the AT section, and quartz crystal rod (48) produced by it, are formed. The quartz crystal rod (32, 48) can be cut in parallel plates, after which a nucleus body (18, 40) is formed the waste (8) is reduced, the nucleus body (18, 40) is restored for a second use, plates (70) without superfluous nuclei are produced and the output is incereased. 10 claims,5 figures
