Superior Material ConstructionEach graphite crucible features a high-purity graphite body reinforced with a high alumina ceramic inner jacket. This combination delivers low thermal expansion and maximum resistance to chemical corrosion, making the crucible reliable even at working temperatures up to 1200C.
Versatile Applications Across IndustriesFrom jewelry production to laboratory research and industrial metal casting, these crucibles are engineered for versatile usage. Their compatibility with both induction and resistance furnaces makes them highly adaptive to different melting processes.
Customizable to Your NeedsChoose from standard round designs or request custom shapes and dimensions to suit your operations. Variability in capacity (300 gm to 10 kg) and lid availability ensures the right crucible for any melting task.
FAQs of Graphite Crucibles With Ceramic Jacket:
Q: How do I choose the correct capacity for a graphite crucible with ceramic jacket?
A: Select the crucible capacity based on your daily metal melting requirements, which can range from 300 grams to 10 kilograms. Custom dimensions and shapes are also available to meet specific operational needs.
Q: What is the advantage of using a high alumina ceramic inner jacket?
A: The high alumina ceramic inner jacket provides enhanced resistance to corrosion from molten metals and fluxes, prolongs crucible life, and supports consistent, efficient thermal conductivity during metal melting.
Q: When should I consider using a lid with the crucible?
A: Using a lid is recommended when you need to minimize oxidation, retain heat, and further reduce melting loss in controlled environments, especially for precious metals such as gold and silver.
Q: Where can these crucibles be used in terms of industries and environments?
A: These crucibles are ideal for jewelry workshops, laboratories, and industrial settings involved in gold, silver, and other high-value metal casting. They are suitable for any environment using induction or resistance heating furnaces.
Q: What steps are involved in the melting process using this crucible?
A: Place the metal to be melted inside the crucible, optionally cover with a lid, and insert it into the compatible furnace. Set the furnace to the desired temperature (up to 1200C), then monitor the melt for the prescribed smelting duration (typically 520 minutes depending on volume).
Q: How does the smooth, non-porous surface benefit the melting process?
A: A smooth, non-porous surface reduces metal adhesion and contamination, ensuring higher purity and yield, while also making the crucible easier to clean and extend its usable lifespan.
