Abstract
This article reports analyzes on a specific quartz crystal block supplied for a specific program on 1/f noise of quartz crystal resonator. This kind of synthetic crystal is usually used to growth new generation of quartz crystal blocks. Description of the blanks realization is presented. Inclusions detection by optical methods are studied. FTIR Spectrometry for mapping alpha values and ICP-MS measurements to qualify amount chemical impurities of the crystal are also given. The results about crystal quality are discussed.
