Platinum Rhodium Crucible (Pt/Rh crucible)
Platinum rhodium (Pt-Rh) crucibles are made from platinum alloyed with 5-10% rhodium, offering enhanced strength and oxidation resistance for extreme temperatures up to 1,700°C. Available in cylindrical, boat-shaped, and custom designs, they’re widely used for single crystal growth, precious metal refining, and corrosive flux reactions in labs and industry. These crucibles come in various purity grades (99.9%-99.95%) and surface finishes (polished/matte) to suit specific applications.
Available in a variety of standard (5-700 ml) and custom sizes, these crucibles ensure uniform thermal conductivity, excellent durability, and minimal contamination during evaporation processes. Pt-Rh crucibles are for sale in competitive price.

Platinum Rhodium (PtRh) Crucible Crucible Application
Platinum Rhodium (Pt-Rh) Crucibles are essential high-temperature labware for precious metal melting (gold, silver, platinum) and advanced material research (single crystal growth, semiconductor synthesis). These ultra-durable crucibles withstand extreme temperatures up to 1700°C, making them ideal for XRF sample preparation, ICP-MS analysis, and catalyst testing. With superior corrosion and oxidation resistance, they’re widely used in metallurgy, aerospace, and nuclear research applications. Available in standard sizes (10mL-100mL) or as custom Pt-Rh alloy crucibles (PtRh5, PtRh10), they’re the top choice for high-purity industrial and laboratory processes.

Comparison of Platinum Laboratory Crucibles for Glass Melting (Case Study)
Abstract: Because of high melting temperature, oxidation and corrosion resistance, platinum crucibles are key tools for wide range of analytical procedures like dissolving in hot hydrofluoric acid, loss on ignition, ash testing and fusion of slag, mineral, cement and glass samples. Pure platinum is the basic material choice, offering relatively low price, on the other hand is quite soft and vulnerable to grain coarsening after prolonged high temperature exposure. Alloying with rhodium increase the material hardness and slows down grain growth, but can be significantly more expensive.
