Introduction
Phoenix Platinum Crucibles & Molds are precision-engineered noble metal labware designed for high-temperature chemical processing, analytical testing, glass melting, and advanced materials research. Manufactured from high-purity platinum or platinum-based alloys, these crucibles and molds offer exceptional resistance to oxidation, chemical corrosion, and thermal shock.
Platinum labware remains the gold standard in environments where contamination must be minimized and long service life is critical. From academic laboratories to industrial quality control departments, platinum crucibles and molds provide consistent performance under extreme thermal conditions.
Detailed Description
Phoenix Platinum Crucibles & Molds are fabricated from high-purity platinum (typically ≥99.95%) or reinforced platinum alloys such as Pt-Rh (Platinum-Rhodium) to enhance mechanical strength at elevated temperatures.
Key performance characteristics include:
High melting point (~1768°C for pure Pt)
Excellent resistance to acids and molten salts
Superior oxidation resistance even at red heat
Minimal contamination risk for sensitive samples
Stable mechanical properties during repeated thermal cycling
Crucibles are available in multiple configurations:
Standard cylindrical crucibles
Tall-form crucibles
Low-form crucibles
Crucibles with fitted lids
Reinforced rim designs
Molds are commonly used for:
Glass bead preparation
Sample casting
Fusion analysis
High-purity material solidification
Platinum molds are particularly valued in XRF (X-ray fluorescence) sample preparation, where contamination from container materials must be avoided.
Precision forming and welding techniques ensure uniform wall thickness and smooth interior surfaces, reducing sample adhesion and simplifying cleaning procedures.
Applications
Phoenix Platinum Crucibles & Molds are widely used in:
XRF fusion sample preparation
Glass and ceramic melting
High-temperature analytical chemistry
Geological sample processing
Precious metal refining
Chemical laboratory research
Advanced material synthesis
In analytical laboratories, platinum crucibles are preferred for gravimetric analysis due to their chemical inertness and dimensional stability.
