WebIt is more precious than silver but with prices more volatile than gold. Platinum has broad chemical resistance although the metal may be dissolved in aqua regia, a highly acidic mixture of nitric and hydrochloric acids, forming chloroplatinic acid, and has an extremely high melting point in excess of two thousand degrees centigrade. WebThis article is purely about the phenomenon of metals that have high melting points, but superalloys (Ni, Co, or Fe based, 1300-1500°C in the upper range), titanium alloys, and tungsten alloys can be considered high …
WebHowever, there is hope for liquid metals: Gallium has a melting point near room temperature and doesn’t share Hg’s toxicity. When Ga was discovered in 1875, Hg had already been known for more than 1000 years and was being used in thermometers, electrochemical reactions, and dental fillings. Web15 lowest melting point metals: Mercury, Francium, Cesium, Gallium, Rubidium, Potassium, Sodium, Indium, Lithium, Tin, Polonium, Bismuth, Thallium, Cadmium, and Lead.

The solubility of gallium in gold is not zero, but is on the order of a few atomic percent. Slightly above the melting point of gallium, the solubility of gold in the liquid is also very small. There are multiple intermetallic phases across the diagram, 4 of which are stable ...
WebNot because of its density or smelly compounds, but because of its high melting point. Very high - over 3 thousand degrees C. After Thomas Edison produced the first commercial electric light in 1879, the race was on to improve on his design - for starters there was the filament - the bit that glows to produce the light but, crucially, doesn't melt.
