Cd, Zn and Te ISOTOPE DEEP PURIFICATION UNIT
Purpose of the development:
106Cd, 116Cd, 64Zn, 67Zn, 128Te, 130Te and other isotope deep purification.
Recommended application field:
Production of radio-pure Cd, Zn and Te isotopes as regards restricted impurities for a variety of applications:
- development of scintillation low-background detectors (116CdWO4, 106CdWO4), 128Te, 130Te;
- photonuclear processes for production of medical-purpose radioactive nuclides (64Zn, 67Zn).
Technical characteristic:
- Mass of original material charge : 250g;
- unit capacity : 50…80 g/hour;
- end product high yield: > 96 % of original charge;
- dimensions of unit, including heater and shields:
height - 400 mm;
diameter - 140 mm;
weight - 3 kg;
- crucible and condenser material : graphite of grade - graphite of grade МПГ-7; heater and shields material : graphite of grade МГ-1 ОСЧ 7-3, ТУ 48-20-9082;
- operating temperature : 350…650 °С;
- vacuum under cold and hot conditions : 1.33 ·10-3 Pa;
- the unit is based on standard furnace units of type СЗВН-0,55.4,5/14-И1.
Advantages over analogues:
- High effectiveness of purification;
- higher yield of end product (> 96 % of original charge);
- minimum irrecoverable losses of material (< 1 %).
The development stage readiness:
Introduced in production
Description of the development:
()
The unit allows to produce radio-pure Cd, Zn and Te isotopes, containing the impurities of
Ni, Cu < 0.2 ppm;
Fe, Mg, Mn, Cr, V, Co < 1 ppm;
Th, U, Ra, K, Rb, In, La, Lu, Sm < 0,1 ppm;
with the minimum irrecoverable losses due to the high cost of those materials.
Operation of the Cd, Zn and Te isotope deep purification unit is based on the principle of material vacuum distillation refining. The unit provides for stage-by-stage purification of isotopes, involving the filtration and distillation process, the potential use of a getter filter, which ensures a deeper purification of cadmium, zinc and tellurium isotopes to remove restricted impurities.
