Quartz Crystals Treatment
DOI: 10.1063/1.3066277
The Signal Corps Laboratories at Fort Monmouth, New Jersey have developed a process for treating quartz crystals which, according to the announcement, “virtually eliminates the aging characteristics of quartz crystals.” Quartz crystals, used to stabilize frequencies in electronics, begin to drift off when they deteriorate with age, which impairs their usefulness and eventually forces their replacement. Under the new process the crystals are superheated to approximately nine hundred degrees Fahrenheit and then cooled slowly. Three Signal Corps physicists, Arthur C. Prichard, Maurice A. A. Druesne, and David G. McCaa, are credited with developing the new process.
