Description

Graphite, Fusion Crucible, Drillpoint, Unpurified, Volume 7.5Cc CAS NO 2319-55-3 is a specialized, machined graphite component designed for high-temperature applications and precision tooling. This product matters for its structural integrity and thermal stability in demanding industrial processes, offering a cost-effective solution where ultra-high purity is not the primary requirement. It is needed by manufacturers and laboratories involved in metal melting, mineral analysis, and the production of wear parts for drilling and machining equipment.

Application

• Fusion and Melting Crucibles: For use in X-ray fluorescence (XRF) sample preparation, fire assay for precious metals, and small-scale non-ferrous metal melting.
• Drill Points and Tooling: Serves as a consumable wear part in precision drilling and machining operations on brittle materials like glass, ceramics, or circuit boards.
• High-Temperature Furnace Components: Used as susceptors, setters, or boats in vacuum and inert atmosphere furnaces for sintering or heat treatment.
• Electrical Discharge Machining (EDM) Electrodes: For creating complex molds and dies through spark erosion due to graphite's excellent electrical conductivity and machinability.
• Foundry and Casting: Employed in permanent mold casting and continuous casting as dies or molds for non-ferrous metals.
• Analytical Chemistry: As electrodes in certain electrochemical analyses or as sample holders in spectroscopic techniques.

Quality Control

Our graphite components are manufactured and inspected to ensure consistent performance for industrial applications. While this is an unpurified, technical grade product, we control key physical parameters such as bulk density, ash content, and particle size to meet application-specific demands. Certificates of Analysis (COA) detailing lot-specific physical properties are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents. The product is not hygroscopic but should be protected from excessive dust and contamination to maintain its performance characteristics.
