Platinum Labware

Platinum Crucible Applications

• Growth of single crystals using the Czochralski or Brigman-Stockbarger process – platinum or Iridium crucibles.
• Chemical and analytical procedures in fluoride and sulphate systems for resolution of oxides, fluorides, carbonates, phosphates, borides, silicates, and other compounds.
• Sampling of silicate rocks, minerals, ores of titanium, niobium, tantalum, zirconium, manganese, chrome, and other minerals and industrial materials – platium or platinum/gold (Pt/Au5%).
• Evaporating and concentrating process of samples of natural waters, processing mediums, mineral acids, and recrystallization of chemical reagents.
• Definition of organic and biological materials, soils, and other ash contents – platinum or platinum/rhodium (Pt/Rh10) for higher hardness and temperature strength.

Platinum Micro Crucibles for Thermal Analysis
Micro crucibles are used in applications including mining industry to certify samples via ICP-ES and ICP-MS techniques. We offer deep-drawn platinum micro crucibles in various sizes. Platinum micro crucibles can be used in place of alumina oxide crucibles (Al2O3) to provide a higher melting point, better thermal conductivity and repeated use at reduced costs.

Phoenix Ring Crucibles for XRF
Platinum/gold (Pt/Au5%) Phoenix ring crucibles for glass fusion for XRF sample analysis including Phoenix gas fusion machines. This alloy provides higher strength and is non-wetting for easier removal of samples.

Optional Platinum and Iridium Crucible Features

• Iridium crucibles for single crystal growth at temperatures up to 2300C, usually for optics crystal growth.
• Welded flat bottom, solid-drawn bottom, and seamless designs
• Platinum crucibles with reinforced rims and tapered walls
• “Dispersion-strengthened” platinum crucibles for increased lifetime and strength at high temperatures
