Choosing the best type of crucible depends on the specific application and the requirements of the process being carried out.
What is the Best Type of Crucible? 5 Crucible Types You Should Know
1. Graphite Crucibles
Graphite crucibles are considered the best for melting metal and induction heating due to their high-temperature resistance.
They can withstand the extreme temperatures encountered in metal casting works and are highly durable.
2. Porcelain Crucibles
Porcelain crucibles are an economical choice for applications with temperatures below 1200 °C.
They are commonly used for chemical analysis and are available in various sizes.
3. Clay-Graphite Crucibles
Clay-graphite crucibles are designed to resist extreme temperatures in foundry operations.
4. Silicon-Carbide Crucibles
Silicon-carbide crucibles are also designed to withstand extreme temperatures in foundry operations.
5. Different Shapes of Crucibles
In terms of shape, crucibles come in different forms such as "A shape" and bilge shape.
"A shape" crucibles may have a slightly rough appearance but are preferred by many due to their lower price.
Bilge shape crucibles have a more finished appearance.
Crucible Usage Tips
It is important to never fill a crucible with a cold metal, as there is a risk of the metal expanding and cracking the container.
Crucibles should also be tested for cracks before each application and replaced if damaged.
Ultimately, the choice of crucible depends on factors such as temperature, chemical compatibility, and the specific needs of the process being carried out.
