A battery made of molten metals - MIT News
网页2016年1月12日 · A new rechargeable, liquid battery made of molten metals and developed at MIT could one day play a critical role in the massive expansion of solar generation, which will be needed to mitigate climate change by midcentury.
Catalytic molten metals for the direct conversion of methane to ...
网页2017年11月17日 · In molten metals, the low-density carbon produced by gas-phase pyrolysis at high temperature floats to the surface of the melt where it can be removed. The highest H 2 yield of 78% at 1175°C was obtained in a 1-m bubble column containing molten tin, which is not thought to be catalytic (15).
23.3: Metallurgy of Iron and Steel - Chemistry LibreTexts
网页2023年7月12日 · Steel is made from iron by removing impurities and adding substances such as manganese, chromium, nickel, tungsten, molybdenum, and vanadium to produce alloys with properties that make the material suitable for specific uses. Most steels also contain small but definite percentages of carbon (0.04%–2.5%).
Metallurgy - Casting, Alloying, Refining | Britannica
网页2024年9月5日 · Metallurgy - Casting, Alloying, Refining: Casting consists of pouring molten metal into a mold, where it solidifies into the shape of the mold. The process was well established in the Bronze Age (beginning c. 3000 bc), when it was used to form most of the bronze pieces now found in museums.
