PTU1023 Herzog Platinum Crucibles & Molds

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.
