Platinum Iridium Crucible (Pt/Ir crucible)
Platinum Iridium (Pt-Ir) Crucibles are premium lab-ware made from high-purity platinum-iridium alloys (PtIr5, PtIr10, PtIr20), offering exceptional heat resistance (up to 2000°C) and corrosion resistance for extreme conditions. These crucibles come in standard shapes (cylindrical, boat-shaped) and custom designs, with options for reinforced rims, lidded versions, and polished/matte finishes to suit specific applications. They are widely used in precious metal refining (gold, platinum group metals), aerospace material testing, semiconductor crystal growth (GaN, sapphire), and nuclear research due to their non-reactive properties and thermal stability.
Available in various sizes (1mL–500mL) and purity grades (99.9%–99.95%), they cater to laboratories, jewelry manufacturers, and high-tech industries requiring ultra-durable, contamination-free melting solutions. For specialized needs, custom alloy compositions and dimensions can be tailored to meet exact research or industrial requirements. Princeton Powder is a leading supplier of Platinum Iridium (Pt-Ir) Crucibles.

FAQ: Platinum Iridium Crucible (Pt/Ir crucible)
What are Platinum Iridium (Pt-Ir) Crucibles?
Platinum Iridium (Pt-Ir) crucibles are high-performance labware made from platinum alloyed with iridium (5%–20%), offering superior heat resistance (up to 2000°C), corrosion resistance, and mechanical strength compared to pure platinum crucibles.
What alloy compositions are offered?
PtIr5 (5% Ir): Balanced cost & performance
PtIr10 (10% Ir): Optimal for most high-temp uses
PtIr20 (20% Ir): Maximum durability for extreme conditions
Are there alternatives to Pt-Ir crucibles?
Pure platinum crucibles (lower cost, but less durable)
Platinum-rhodium (Pt-Rh) crucibles (excellent for 1700–1850°C)
Ceramic crucibles (alumina, zirconia – but less inert)
