Boron Nitride Semi-Sector Grooved Crucible High Purity BN Ceramic Mold for Precious Metal Melting & Ceramic Sintering

Boron Nitride Semi-Sector Grooved Crucible High Purity BN Ceramic Mold for Precious Metal Melting & Ceramic Sintering

Our semi-sector grooved boron nitride (BN) ceramic crucibles are precision-engineered from high-purity hot-pressed BN for extreme high-temperature applications. Featuring a unique semi-sector (half-moon) design with a precision-machined inner groove, these crucibles can be assembled into full circular molds to accommodate large-volume processing. Leveraging BN’s exceptional non-wetting properties, chemical inertness, and thermal stability, they are the ideal choice for precious metal melting (gold, platinum, palladium) and high-performance ceramic sintering, ensuring zero contamination and easy demolding of finished products.
