Description of the activity
X-ray diffraction laboratory has two diffractometers for powders, Philips. X-ray diffractometry allows qualitative and quantitative analysis of crystalline phases. The technique is non-destructive and also permits the determination of other physical characteristics of the samples, such as its crystallinity.
In our laboratory, qualitative and semi-quantitative analysis (RIR method) are performed of natural and artificial materials including:
- minerals and rocks,
- asbestos compounds,
- glasses,
- ceramics,
- cements,
- ancient mortars,
- pharmaceuticals products,
- slags,
- bone specimens,
- crystalline organic compounds.
- particles with size fraction <2-4 microns for the identification of clay minerals.
The laboratory also performs archaeometric analyses on works of art, especially on stone building materials and their decay products and on ancient mortars, ceramics, slag, etc. (collaborations with Opificio delle Pietre Dure, Superintendence of Cultural Heritage, external companies, Italian and foreign universities, etc.). On going research projects and collaborations are with the Italian CNR institutes in archaeometric and geological - mineralogical fields.
The laboratory collaborates also with important Italian industries on the analyses of materials from environmental and technological fields and analyses on health materials with companies dealing with work environments. Moreover analyses on pharmaceuticals products for quality control and analyses on artificial materials (mortars and cements) were frequently carried out .
Instruments
1 - X-ray diffractometer for powders Philips Model PW 1050/37, with a Panalytical X’Pert PRO data acquiring system, operating with a Cu anode, a graphite monochromator (limit of detection 4%);
2 - X-ray powder diffractometer Philips Model PW 1050/37, with a Panalytical X’Pert PRO data acquiring system, operating with a Cu anode, a graphite monochromator (limit of detection 4%).
How to access
The internal staff of the Department can access following the course of the Manager in the use of the diffractometers and after having read the Internal Regulations of the Laboratory. Personnel outside the Department cannot access it.
