Though virtually unseen in nature, high-purity bismuth can form distinctive, colorful hopper crystals. It is relatively nontoxic and has a low melting point just above 271 °C (520 °F), so crystals may be grown using a household stove, although the resulting crystals will tend to be of lower quality than lab-grown crystals.

2024年8月18日 · To make bismuth crystals, start by melting the bismuth in a tall, narrow pot over a stove outdoors. Once the bismuth has melted, scrape off and dispose of the shiny layer on top.

2024年6月17日 · Bismuth is chemically similar to arsenic and antimony but is less reactive than both. It has a low melting point (271.5 °C or 520.7 °F) for a metal, allowing it to be melted down and cast into shapes easily. This metal is also one of the few substances that expand as it solidifies from its molten state, a property it shares with water.

Bismuth metal is brittle and so it is usually mixed with other metals to make it useful. Its alloys with tin or cadmium have low melting points and are used in fire detectors and extinguishers, electric fuses and solders.

2025年1月8日 · Bismuth is thus a useful component of type-metal alloys, which make neat, clean castings; and it is an important ingredient of low-melting alloys, called fusible alloys, which have a large variety of applications, especially in fire-detection equipment.

Melting point of Bismuth is 271°C. Boiling point of Bismuth is 1560°C. Note that, these points are associated with the standard atmospheric pressure. Thermal conductivity of Bismuth is 8 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K.

2014年11月19日 · Compared to other metals, bismuth has a relatively low melting point, 271°C, and when it is alloyed with tin and lead, it melts at even lower temperatures. This characteristic opens up a range of interesting applications for bismuth-containing compounds.

Bismuth metal has a melting point of 271 deg C (520 deg F) and a boiling point of 1,560 deg C (2,840 deg F). On freezing, molten bismuth expands 3.3% by volume, a property shared by only one other element, gallium. Bismuth forms compounds in the +3 and +5 oxidation states; the +3 state is the more stable of the two.

2024年8月25日 · Bismuth is a heavy, brittle metal with the atomic number 83 and the symbol Bi. It is known for its distinctive, iridescent appearance when oxidized, displaying hues of pink, blue, and green. The metal has a relatively low melting point of about 271.4°C (520.5°F) and is often found in nature as a compound rather than in its pure form.

2020年11月11日 · Melting point of Bismuth is 271°C. Boiling point of Bismuth is 1560°C. Note that, these points are associated with the standard atmospheric pressure. In general, boiling is a phase change of a substance from the liquid to the gas phase. The boiling point of a substance is the temperature at which this phase change (boiling or vaporization) occurs.
