Descrizione

Descrizione generale

This Standard Reference Material (SRM) was prepared for use as an external or internal 20φ (large d-spacing) calibration standard for powder diffractometry. The material is synthetic fluorophlogopite mica and is best suited for reflection diffractometry as pressed samples have a high degree of preferred orientation in which only the 00l reflections have significant intensity. The mica was ground to pass a 75μm (200 mesh) sieve. For more information,please refer to the COA and SDS.
