FIELD: material for production of assay stone, in particular standard determination.
SUBSTANCE: assay stone is made from oxide ceramic comprising BeO-TiO2. Material affords the ability to obtain assay stone of regular geometric form with surface, electrical and mechanical properties meeting the requirement for material used in assaying control. Claimed material in useful in standard determination followed by electrochemical recovery of precision metals from solution after assaying control.
EFFECT: material of homogeneous structure; decreased time of precision metal recovery after assaying control.
