Vaporization of thallium (III) oxide and thallium activities in thallium superconductors

The Journal of Chemical Physics, 1991
Vaporization reactions for both Tl2O3(s) and a Tl superconductor sample, primarily Tl2Ba2Ca2Cu3Oy(s) (Tl-2223), were determined. The vapor species were examined by Knudsen effusion mass spectrometry at temperatures in the range 657 to 773 K for Tl2O3(s) and 672 to 836 K for Tl-2223. Additional experiments with thermogravimetric analysis (TGA) equipment

Thallium nonstoichiometry in 2212-thallium cuprate

Journal of Solid State Chemistry, 1992
The study of thallium nonstoichiometry in the thallium 2212 cuprate by X-ray diffraction and electron microscopy has allowed a significant homogeneity range to be isolated, Tl{sub 2{minus}x}Ba{sub 2}CaCu{sub 2}O{sub 8{plus minus}{delta}} with 0{le}x{lt}0.4.

Thallium

2009
Publisher Summary Thallium (Tl) is a soft, bluish-white metal that occurs naturally in the earth's crust. Thallium is a highly toxic element, and salts of Tl are colorless, odorless, and tasteless. Due to their highly toxic nature, delayed symptoms, and lack of taste or odor, Tl salts have been used for suicide attempts and in the intentional ...

Thallium toxicity

Toxicology Letters, 1998
Thallium (T1+) is a toxic heavy metal which was accidentally discovered by Sir William Crookes in 1861 by burning the dust from a sulfuric acid industrial plant. He observed a bright green spectral band that quickly disappeared. Crookes named the new element 'Thallium' (after thallos meaning young shoot).

Determination of indium and thallium in indium-thallium alloys

Talanta, 1971
The thallium-indium alloys were dissolved in sulphuric acid (1 + 1). In this medium thallium remained in the univalent state and could be determined directly, without a separation, by an oxidation-reduction titration with potassium bromate. The indium was determined directly with an EDTA titration.
