Administrative data
Link to relevant study record(s)
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2009-09-15 to 2009-10-01
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The crystalline strucutres were identified by X-ray diffraction of the powdered sample, using a BRUKER Theta-Theta model D8 Advance diffractometer. Using the resulting diffractogram, the mineralogical species present are identified using the JCPDS files for pure crystalline phases.
- GLP compliance:
- not specified
- Physical state at 20°C and 1013 hPa:
- solid
- Form:
- powder
- Colour:
- yellow
- Odour:
- odourless
- Substance type:
- inorganic
- Conclusions:
- The crystalline structures identified in the sample are listed below:
Major phase:
Bnid = Bnidheimite (Pb2Sb2O7).
Minor phases:
Cer=Cerianite (CeO2).
PbO = Lead oxide (PbO).
Very minor phases:
Co = Corundum (Al2O3).
Clin = Clinocervantite (SbO2)
AlOP = Aluminium phosphate
(AlPO4) NaOSb = Sodium oxide and antimony
(Na2Sb4O7).
CaHOPb = Calcium hydroxide and
lead (Ca2Pb2O5(OH)2)
