Abstract
Methods for purifying reaction precursors used in the synthesis of inorganic compounds and methods for synthesizing inorganic compounds from the purified precursors are provided. Also provided are methods for purifying the inorganic compounds and methods for crystallizing the inorganic compounds from a melt. γ and X-ray detectors incorporating the crystals of the inorganic compounds are also provided.
Claims17
A method for forming a purified thallium compound, the method comprising:
- combining:
- at least one starting oxidized thallium compound or at least two solid starting inorganic precursor materials, wherein the at least two starting inorganic precursors are elemental transition metals, elemental semi-metals, halides, metal halides, metal chalcogenides, or a combination thereof and at least one of said at least two solid starting inorganic precursor materials comprises oxidized thallium;
- and a carbon powder in a reaction vessel;
- sealing the reaction vessel under vacuum;
- melting the at least one oxidized thallium compound or the at least two solid starting inorganic precursor materials to form a melt, wherein the carbon from the carbon powder reduces the thallium oxide to form a reduced, thallium compound or a reduced, thallium-containing inorganic precursor material;
- and
- solidifying the melt.
