Leco® Platinum Crucibles & Molds Description

Platinum is a remarkable transition metal, recognized for its density, malleability, and ductility. Its lustrous, silver-white appearance and high resistance to chemical reactions make it a highly sought-after material. Unlike many other metals, platinum remains impervious to oxygen and water, and it dissolves only in a mixture of aqua regia or when exposed to fused alkalis.

FAQ

A crucible is a heat-resistant container designed to hold materials during high-temperature processes such as melting, alloying, or chemical reactions. They’re essential in metal casting, laboratory analyses, and even certain thin-film deposition systems.

Crucibles are usually made from ceramics like alumina, zirconia, silicon carbide, or magnesia due to their high melting points and chemical inertness. Graphite and metal (e.g., steel) crucibles are also used for lower temperature applications.

The ideal crucible depends on the temperature and chemical nature of the process. Always select a crucible material with a melting point significantly higher than that of the material being processed and one that is chemically compatible to prevent reactions or contamination.

Always wear appropriate personal protective equipment (PPE) such as heat-resistant gloves, face shields, and aprons. Use proper tongs for handling, ensure adequate ventilation, and follow established protocols to avoid thermal shock and accidental spills.

Prior to use, crucibles are usually “dried” or pre-fired to remove moisture and avoid thermal shock. Some applications recommend a seasoning or “dressing” process to improve performance and extend the crucible’s lifespan.

Crucibles should be stored in a dry, well-ventilated area on wood shelving or other non-abrasive supports—not directly on concrete or metal floors—to avoid damage. They should also not be nested together to prevent chipping or cracking.

Yes, most crucibles are designed for multiple uses if they’re properly maintained and cleaned. However, frequent use at extreme temperatures or for reactive materials may eventually degrade them, in which case replacement is necessary.

Common challenges include cracking from rapid temperature changes (thermal shock), contamination from residual materials, and wear or erosion from high-temperature exposure. Following proper handling and maintenance guidelines helps mitigate these issues.

Allow the crucible to cool completely, then remove any residues with a suitable scraper or chemical cleaner if recommended. Some crucibles benefit from an acid wash to remove stubborn deposits—but always follow the manufacturer’s guidelines to prevent damage.

Ensure the crucible is pre-heated and free of moisture. Load the material slowly and evenly using appropriate tools to prevent splashing or uneven heating. For heavy or large pieces, use tongs or specialized equipment to maintain safety and consistency.

In metal casting, crucibles are used to melt and hold metals for forming alloys or casting components. In evaporation processes (e.g., thin-film deposition), they heat materials to their vaporization point, allowing controlled deposition onto substrates.

Their ability to withstand extreme temperatures and resist chemical reactions makes crucibles indispensable. They enable precise control over high-temperature processes in metallurgy, materials science, and chemical analysis, ensuring product quality and process reliability.
