What is the definition of crucible in chemistry?

Asked by: John Hilton

crucible \KROO-suh-bul\ noun. 1 : a vessel in which metals or other substances are heated to a very high temperature or melted.

What does crucible mean in chemistry?

A crucible is a vessel in which metallic elements are melted to be cast into new objects or to create a new alloy. Crucibles are traditionally made from ceramic materials, which can withstand very high temperatures.

What is the crucible in science?

A crucible is a ceramic or metal container in which metals or other substances may be melted or subjected to very high temperatures. While crucibles were historically usually made from clay, they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents.

What is the full meaning of crucible?

A crucible is a severe test or trial or an extremely challenging experience. This figurative sense of crucible is based on the literal meaning of the word: a heat-resistant container used to melt metals. Crucible in the literal sense is used in the context of metallurgy, the science of working with and refining metals.

What is a crucible and lid in chemistry?

A crucible is a type of laboratory glassware designed to melt or burn solid chemicals over a burner. Made from heat-resistant ceramic or metal, they’ll withstand high temperatures up to 1050° Fahrenheit. Shop a selection of low form and high form cast crucibles with lids, ranging in size from 15 ml to 50 ml.

What is quartz crucible?

Full Description of Quartz Crucible



The QC (Quartz-crucible) of high purity Silica (SiO2) material, is a transparent container which is resistant to extremely high temperatures as well as being chemically inert to get non-contaminated results.

Why is graphite used to make crucibles?

Chemically, graphite is stable and inert with most elements. Being resistant to chemicals and having a high melting point and also because it is a good conductor of heat, graphite is used to make crucibles.

What type of crucible is used for aluminum?

Carbon-bonded and ceramic-bonded clay graphite and silicon carbide crucibles are widely use in melting and holding aluminum and aluminum alloys, aluminum-bronze, copper and copper-based alloys, cupro-nickel and nickel-bronze alloys, precious metals, zinc and zinc oxide. Crucibles also are used in melting cast iron.

Why is crucible metal used in melting non ferrous metal?

The main use of graphite crucibles is in the casting process. They are ideal for melted metal processes because they are non-reactive and able to survive extremely high temperatures.

What is graphite crucible?

Graphite crucibles are high quality melting crucibles. They can be used at temperatures up to 1600C (2900^oF) and are suitable for melting and refining precious metals, base metals, and other products.

How hot can a crucible get?

Graphite Crucible Temperature Range can go as high as 5000°F and can be used in furnaces and high heat processes. Graphite crucibles have many applications within the foundry, laboratory testing, valves, sprinklers, and other heavy-duty products. Graphite crucibles are not very porous.

How do you make a crucible melt gold?

What you need is a kitchen knife. The spoon. And potato cut your potato in. Half. You shape it up using a teaspoon. And pretty much already to start melting your.

Can you use clay for a crucible?

You can easily make your own crucibles from materials that have a high melting point, prefiring them as far above the service temperature as possible. Simple fire clay is commonly employed.

How do you fire a crucible?

To use the Crucible, place it above any heat source (e.g., Lava, Fire, a lit Furnace, or even a Torch). Right-click with an eligible block to place that block into the Crucible, then wait for it to melt.

How do you melt steel in a crucible?

So what my plan is is to mix equal parts cement crushed up fire brick and sand. And then just you know add enough water to get that to a paste.

Can cast iron be used as a crucible?

What it looks like. And give you a quick look inside it and this crucible has 25 melts in it with cast iron.

How is crucible steel made?

Crucible steel is steel made by melting pig iron (cast iron), iron, and sometimes steel, often along with sand, glass, ashes, and other fluxes, in a crucible. In ancient times steel and iron were impossible to melt using charcoal or coal fires, which could not produce temperatures high enough.
