Compare Thallium vs Mercury| Compare properties

Thallium metal is mostly used for producing photoelectric cells. In thermometer's mercury alloy has 8% of thallium, as it has a melting point lower than 20°C. It is a liquid metal at room temperature, but it is a toxic heavy metal and hence many uses of mercury are under review or phased out.

Melting Point of Chemical Elements - Periodic Table

Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.The chemical symbol for Hydrogen is H. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass.

Amalgam (chemistry) - Wikipedia

Thallium amalgam has a freezing point of −58 °C, which is lower than that of pure mercury (−38.8 °C) so it has found a use in low temperature thermometers.

Prices of chemical elements - Wikipedia

This is a list of prices of chemical elements.Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.It is followed by caesium, iridium and palladium by mass and iridium, gold and platinum by volume.

Thallium - chemeurope.com

thallium amalgam is used in thermometers for low temperature, because it freezes at -58 °C (pure mercury freezes at -38 °C). In addition, 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 ...

Specific Heat of Mercury and Thallium between 0.35 and 4.2°K

The specific heat of mercury and thallium were measured between 0.35 and 4.2°K. In the normal state below 0.7°K the mercury results are given by: C n =1.79T+5.23T 3 mJ/mole deg. The coefficient α of the T 3 term corresponds to a value of the Debye parameter Θ 0 of 71.9°K. For temperatures higher than 0.7°K, the lattice specific heat deviates above the T3 law.
