Clay Graphite Crucible

In the demanding world of metallurgy, foundries, and precious metal refining, the choice of melting crucible directly dictates efficiency, material purity, and operational safety. Inferior crucibles can lead to thermal shock damage, chemical erosion, and inconsistent melting, resulting in wasted energy, compromised metal quality, and costly downtime. The need for a durable, reliable, and high-performing melting vessel is paramount for optimal production.

The DECENT Clay Graphite Crucible is engineered to excel in these extreme environments. Crafted from an advanced blend of high-purity graphite and specialized clay, it offers exceptional thermal conductivity for rapid, uniform heating, significantly reducing melting times. Its robust construction provides outstanding resistance to high temperatures, thermal shock, and chemical corrosion from molten metals and fluxes. With a smooth inner wall preventing adhesion and ensuring the purity of your melts, the DECENT Clay Graphite Crucible delivers consistent, long-lasting performance for all your metal casting and refining needs.

Equipment Construction

  • Materials: Made from a precise mixture of natural graphite and clay (e.g., refractory clay).
  • Inner Wall: Smooth internal surface to prevent molten metal leakage and adhesion.
  • Thermal Expansion: Features a small thermal expansion coefficient during high-temperature operation.
  • Thermal Shock Resistance: Designed to withstand rapid cooling and heating strains.
  • Chemical Stability: Possesses strong corrosion resistance to both acidic and alkaline solutions.
  • Forming Process: Often manufactured using advanced pressing techniques for density and uniformity.
  • Size Versatility: Available in a diversity of sizes, from small laboratory to large industrial capacities.
  • Durability: Dense, uniform, defect-free material ensuring high strength and long service life.
