Three graphite crucibles were purchased and were each filled with one of the different materials and carbon. Crucible 1 contained the Pacer material and carbon layered in about 12-14 alternating layers. Crucible 2 contained the commercially available pellets from

A Rapid Determination of Small Amounts of Lead in Zinc

A carbon crucible was used for the zinc pot. This penai tted querichtng the alloy without pouring or cooling it. Also, it is accepted that carbon is not soluble in zinc(9,10). Because of its insolu-bility, a carbon arc electrode was used for the stirrer. By regulating gas

Experimental research of crucible steel: a new insight

This paper describes experimental archaeo-metallurgical research on crucible steel, executed as a master project to obtain the master degree in conservation. After evaluating the results of different manufacturing techniques, the so-called Georgian crucible steel

Alchemy (ALCH

Common elements melted with a graphite crucible are aluminum, brass, gold, and silver. Crucibles also have a low reactivity towards molten metals, making it a great tool to use in the lab. We will go into the different types of crucibles and more details about them in Lesson Eight.

Silicon Carbide Crucible, Silicon Carbide Graphite Crucible

Apart from the large SiC graphite crucible sizes, there are also sizes below the 30kg metal holding capacity. However, when smelting pure gold of 1 to 30 kg sizes, a silicon carbide graphite crucible or a graphite crucible is the best choice, this ensures that your

Joseph Dixon

Dixon became most widen known in connection with the crucible works that bear his name, having invented the plumbago, or graphite, crucible as now made. He established his factory in Salem, Massachusetts, in 1827, removing it to Jersey City in 1847, and, with improvements and additions, it has grown into the largest factory of its kind in the world.

Graphite: Mineral information, data and localities.

Natural graphite is used for refractories, batteries, steelmaking, brake linings, foundry facings and as a lubricant. It also used, when powdered and mixed with clay, to produce the lead in pencils. About 7% of worldwide production is used this way.

Gold Melting Pot, Motor Tilting Metal Melting Furnace

To collect gold from mines, its ore or from gold dust, gold concentrate is combined with flux, such as borax or other materials of mixtures in a crucible. The flux acts to decrease the melting temperature and viscosity of non-gold materials in the concentrate so that they are easily separated from the gold during the melting process.

A History of Iridium

Iridium is as hard as steel, and the crucible is almost unaffected by any mechanical treatment that can reasonably be applied to it." Crookes, well in advance of his time, went on to report that his iridium crucibles, one of which still survives in the company's possession, were resistant to the fusion of many fluxes, including caustic soda, and were un-attacked by molten lead, zinc
