Thallium Metal(TI Metal)

Product Information

Thallium is a chemical element with the symbol Tl and atomic number 81. It is a gray post-transition metal that is not found free in nature. When isolated, thallium resembles tin, but discolors when exposed to air. Thallium tends to form the +3 and +1 oxidation states. The +3 state resembles that of the other elements in group 13 (boron, aluminium, gallium, indium). However, the +1 state, which is far more prominent in thallium than the elements above it, recalls the chemistry of alkali metals, and thallium(I) ions are found geologically mostly in potassium-based ores, and (when ingested) are handled in many ways like potassium ions (K+) by ion pumps in living cells. Commercially, thallium is produced not from potassium ores, but as a byproduct from refining of heavy-metal sulfide ores. Approximately 65% of thallium production is used in the electronics industry, and the remainder is used in the pharmaceutical industry and in glass manufacturing.[7] It is also used in infrared detectors. The radioisotope thallium-201 (as the soluble chloride TlCl) is used in small amounts as an agent in a nuclear medicine scan, during one type of nuclear cardiac stress test.

This is the deadliest element . Thallium is far more dangerous than mercury or even white phosphorus. Locked inside this ampule this lead-like metal seems harmless enough but we highly highly recommend you resist the urge to break it open to play with the contents. This is because thallium, unlike most other chemicals, can penetrate unbroken skin, poisoning you invisibly. Respect it and keep it between you and the glass and all will be ok! There aren't many uses for this metal in large part due to its toxicity but one curious application is in very low temperature thermometers. When alloyed with mercury the metal will remain liquid as cold as 60°C below zero!1

Applications of Thallium Metal

A mercury–thallium alloy, which forms a eutectic at 8.5% thallium, is reported to freeze at −60 °C, some 20 °C below the freezing point of mercury. This alloy is used in thermometers and low-temperature switches. In organic synthesis, thallium(III) salts, as thallium trinitrate or triacetate, are useful reagents for performing different transformations in aromatics, ketones and olefins, among others.[58] Thallium is a constituent of the alloy in the anode plates of magnesium seawater batteries.[7] Soluble thallium salts are added to gold plating baths to increase the speed of plating and to reduce grain size within the gold layer

Thallium(I) bromide and thallium(I) iodide crystals have been used as infrared optical materials,

Thallium(I) sulfide's electrical conductivity changes with exposure to infrared light, making this compound useful in photoresistors.[

Research activity with thallium is ongoing to develop high-temperature superconducting materials for such applications as magnetic resonance imaging, storage of magnetic energy, magnetic propulsion, and electric power generation and transmission. The research in applications started after the discovery of the first thallium barium calcium copper oxide superconductor in 1988.[51] Thallium cuprate superconductors have been discovered that have transition temperatures above 120 K. Some mercury-doped thallium-cuprate superconductors have transition temperatures above 130 K at ambient pressure, nearly as high as the world-record-holding mercury cuprates
