Thallium trioxide

Metal Oxides. Hydrogen sulfide may ignite in contact with barium dioxide, chromium trioxide, copper oxide, lead dioxide, manganese dioxide, nickel oxide, silver mono- and dioxides, sodium peroxide, and thallium trioxide. It may explode in the presence of air and mixtures of calcium or barium oxide with mercury or nickel oxide.5... 

Violence of reaction depends on concentration of acid and scale and proportion of reactants. The following observations were made with additions to 2-3 drops of ca. 90% acid. Nickel powder, becomes violent mercury, colloidal silver and thallium powder readily cause explosions zinc powder causes a violent explosion immediately. Iron powder is ineffective alone, but a trace of manganese dioxide promotes deflagration. Barium peroxide, copper(I) oxide, impure chromium trioxide, iridium dioxide, lead dioxide, manganese dioxide and vanadium pentoxide all cause violent decomposition, sometimes accelerating to explosion. Lead(II) oxide, lead(II),(IV) oxide and sodium peroxide all cause an immediate violent explosion.

The physical properties of the metal (Table II) resemble those of thallium, lead and bismuth, its neighbors in the Periodic Table, rather than those of tellurium, its lower homologue. The low melting and boiling points are particularly noteworthy an attempted study of the Hall effect in polonium metal has also been reported (90). In chemical properties the metal is very similar to tellurium, the most striking resemblance being in its reactions with concentrated sulfuric acid (or sulfur trioxide) and with concentrated selenic acid. The products are the bright red solids, PoSOs and... 

Ignites on contact with metal oxides (e.g., barium peroxide, chromium trioxide, copper oxide, lead dioxide, manganese dioxide, nickel oxide, silver(I) oxide, silver(II) oxide, sodium peroxide, thallium(III) oxide, mercury oxide, calcium oxide, nickel oxide), oxidants (e.g., silver bromate, heptasilver nitrate octaoxide, dibismuth dichromium nonaoxide, mercury(I) bromate, lead(II) hypochlorite, copper chromate, fluorine, nitric acid, sodium peroxide, lead(IV) oxide), rust, soda-lime + air. Reacts violently with NI3, NF3, p-bromobenzenediazonium chloride, OF2, F2, Cu, CIO, BrFs,...

A 34-year-old woman with acute promyelocytic leukemia was given arsenic trioxide solution 0.1%, 10 ml/day for 7 days. A generalized skin rash appeared, and her serum transaminases rose. An electrocardiogram was normal. A second course of arsenic trioxide was used about 3 months later. She felt palpitation and mUd dyspnea and had complete atrioventricular block. Echocardiography showed a normal left ventricle. A thallium myocardial perfusion scan did not show a perfusion defect. Arsenic trioxide was withheld. Sinus rhythm returned 3 days later. Complete atrioventricular block recurred later when arsenic trioxide was re-administered, albeit in a lower dosage for a shorter period of time.
