50ml flanged pure zirconium crucible, 99.9%

Baoji Freelong New Material Technology Development Co., Ltd. loated in Baoji City--China's Titanium Valley,we are mainly doing Zirconium,Titanium,Nickel,Niobium,Tantalum etc metal material and other alloy's produce,OEM and Sales.and also exporting the goods what we make. we have a lot of trustful clients and partner.and also we were authority by some firms.At present,we were build our relationship with Australia,Korea,German,US,UK,Malaysia,AZ,Middle East,Taiwan,Etc. Our company always take the quality and service as our responsibility,We always get close even match the quality what our customer wanted and as for quality,we never say no and no reason for quality failure.

The mainstream material for laboratory-grade pure zirconium crucibles is American Standard Zr702 (UNS R60702), an industrial-grade pure zirconium with high purity and few impurities, belonging to the category of metallic zirconium crucibles.

Zirconium crucibles offer excellent resistance to high temperatures and highly corrosive chemicals, making them an ideal, cost-effective alternative to platinum crucibles for laboratories.
Zirconium crucibles are engineered for durability and high performance in fusion sample preparation processes. Made from high-purity zirconium, these crucibles and lids exhibit exceptional corrosion and thermal shock resistance, helping to ensure consistent analytical results

Key Features:
**High Temperature Resistance:** Melting point approximately 1852℃, under vacuum/argon inert atmosphere:
Long-term stable operation at ≤1600℃, short-term up to approximately 1700℃ without softening or deformation.
**Extremely Strong Chemical Stability:** Does not react with titanium, nickel, niobium, tantalum, rare earth elements, or many high-temperature alloy melts;
Resistant to acid and alkali corrosion, non-stick, and does not contaminate experimental samples, suitable for high-purity experiments.
**Excellent Thermal Shock Resistance:** Low coefficient of thermal expansion, less prone to cracking under rapid heating and cooling, with a service life far exceeding that of corundum and quartz crucibles.
**Dense, Non-Porous Material:** Mostly seamless spun/welded, with smooth inner walls, easy to clean and residue-free, suitable for micro-volume and precision experiments.
**Usage Atmosphere Restrictions:** Can only be used in vacuum, argon, or inert atmospheres; In oxygen-rich air environments exceeding 500℃, rapid oxidation, peeling, and embrittlement will occur; high-temperature air use is strictly prohibited.

Grades: Zr702, Zr705, R60001, R60901

Capacity: 5–50 ml (custom fabrication based on drawings available)

Types: Low-form, flanged, straight-wall, tapered-wall, and cylindrical

Surface Finish: Bright

Wall Thickness: 1 mm, 2 mm, or customizable

Service Life: Crucibles with a 2 mm wall thickness offer a longer service life than thin-walled versions and can be reused over 100 times.

Main Applications

High-temperature vacuum melting, small-sample metal melting experiments
Rare earth materials, high-purity alloy batching and sintering
High-temperature digestion and ashing experiments of chemical corrosion samples
Preparation of special high-temperature materials in research institutes and university laboratories
