Gypsum-bonded investment and dental precision casting (IV) transformation of III-CaSO4 to II-CaSO4.
The degree of III-CaSO4 to II-CaSO4 transition was estimated on wet specimens, 25 mm in diameter and 50 mm high, prepared from a gypsum-bonded investment for quick casting. After 30 min from mixing the specimens were heated in a 700 degrees C furnace until a specimen temperature of 200 degrees C to 700 degrees C was reached. The estimation was made by measuring mass changes of the specimens bef...
متن کاملAbundant Bassanite and Γ-caso4 in Mil 03346,168 Meteorite
MIL03346 meteorite: It is a martian meteorite (nakhlite) collected from Miller Range, Antarctica. It contains variety of hydrous Caand Fe 3+ -sulfates, and other H2O/OH-bearing species, thus has been extensively studied, with a purpose to build the links to aqueous alteration processes on Mars [4-9]. The martian origin of Ca-sulfates and jarosites in MIL 03346 is validated by the finding of the...

متن کاملDYSPROSIUM DOPED CaSO4 FOR HIGH SENSITIVITY X AND GAMMA-RAYS DETECTORS
The crystalline substances are the most used for Thermoluminescent Dosimetry (TLD) purposes. The crystalline structure allows for a controlled impurification with activators in order to improve their dosimetric parameters. The activators introduced into the crystalline network [1], enhance the number of electrons and hole traps inside the forbidden band. In the first step, immediately after the...
متن کاملStudy on the response of indigenously developed CaSO4:Dy phosphor-based neutron dosemeter.
In the present paper, we report the indigenous development of a neutron-sensitive thermoluminescent dosemeter (TLD) based on CaSO4:Dy Teflon TL disc. The study includes indigenous development of a neutron dosemeter and its response in terms of operational quantity to different energies of neutrons under various irradiation conditions. It was found that the thermal neutron sensitivity of the CaS...
