Antwort What is the best type of crucible? Weitere Antworten – What is the best kind of crucible
Graphite Crucibles: They are the best crucibles for melting metal and induction heating because of their high-temperature resistance. Porcelain Crucibles: Economical choice for applications with temperatures below 1200 °C.Graphite Crucibles for Metal Melting also have impressive temperature resistance, typically up to 3000°C. However, their performance can be influenced by the specific type of graphite used and impurities in the material. For extremely high-temperature applications, ceramic crucibles may have a slight edge.So how do you select the right crucible for your operation from the extensive range of crucible types and materials available to you
- The capacity, dimensions and type of your furnace.
- The specific alloy or range of alloys you melt.
- The melting and/or holding temperatures you maintain.
What makes a good crucible : In addition, the crucible materials should also have good strength even when extremely hot. Crucibles come in a variety of metal constructions, such as tungsten crucibles, zirconium crucibles, and etc. These materials can resist extreme temperatures in typical experiments and operations.
Are graphite crucibles good
It has unique features such as high temperature resistance (withstand up to 2760 °C), excellent acid and alkali resistance, good thermal shock resistance, excellent thermal/electrical conductivity and high mechanical strength. It is widely used for induction heating and metal melting, such as Ag, Au, Cu and Al metals.
What is the best crucible for melting steel : Quartz crucibles are suitable for melting iron, aluminum, stainless steel, platinum, gold, palladium, etc. Graphite crucibles are suitable for melting copper, brass, gold, silver, zinc, lead, and other non-ferrous metals and their alloys.
The carbon binders and graphite in crucibles would burn when exposed to heat. To prevent this, glass like glazes are applied to the exterior and interior of the finished crucible to seal it from oxygen. The glaze is designed for resistance to chemicals and thermal shock as well as damage from use.

Sintered vitreous carbon crucible. Vitreous carbon is resistant to very high temperatures up to 3000°C in inert gas.
Why do crucibles not melt : Crucibles are traditionally made from ceramic materials, which can withstand very high temperatures. The material of your crucible should always have a much higher melting point than that of the materials you are heating.
What crucible to use for melting steel : Quartz crucibles are suitable for melting iron, aluminum, stainless steel, platinum, gold, palladium, etc. Graphite crucibles are suitable for melting copper, brass, gold, silver, zinc, lead, and other non-ferrous metals and their alloys.
Why use platinum crucible
Platinum crucibles are routinely used for high-temperature sample fusion, owing to the material's extremely high melting point and low chemical reactivity even at elevated temperatures.
Quartz crucibles are suitable for melting iron, aluminum, stainless steel, platinum, gold, palladium, etc. Graphite crucibles are suitable for melting copper, brass, gold, silver, zinc, lead, and other non-ferrous metals and their alloys.Theoretically, you can glasses in graphite crucible melt under protective atmosphere and then slowly to cool with the furnace, but it does not work with all glasses. Because of the high viscosity of this glass I couldn't cast in a mold, I guess even if I try to cast most of the sample will remain in the crucible.
