Product Description

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.

Product Description:
Zirconium crucibles offer excellent resistance to high temperatures and highly corrosive chemicals, making them an ideal choice for laboratories seeking a cost-effective alternative to platinum crucibles.
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.

1. Material Standards
The laboratory-grade pure zirconium crucible uses ZR702 high-purity metallic zirconium, with a zirconium content ≥99.2%~99.95% (99.9% ultra-high purity is preferred for laboratory use), hafnium impurities ≤4.5%, and low oxygen internal control.

Melting point: 1852℃, normal operating temperature ≤1600℃, short-term vacuum temperature up to 1750℃;

Density: 6.51g/cm³, low coefficient of thermal expansion, resistant to rapid heating and cooling, and resistant to thermal shock cracking;

Core characteristics: Resistant to hydrofluoric acid, concentrated strong alkalis, molten alkali salts, and various strong acid corrosion; does not react with rare earth, precious metals, or active metal melts at room temperature/high temperature; no element precipitation or sample contamination; non-magnetic, suitable for magnetic field environment testing.

Precautions for Laboratory Heat Treatment

 Highly resistant to most reagents
 Soluble in hydrofluoric acid
 Withstands temperatures up to 900°C
The low-form crucible is made of zirconium alloy with a thickness of 0.89 mm. Oxidation begins upon prolonged exposure to air at temperatures above 550°C. Use with fluoroboric acid or fluorosilicic acid is not recommended. Suitable for high-temperature fusion in the reducing flame of a burner.

Quality Control and Testing

Each product undergoes rigorous inspection before shipment:

Dimensional Inspection: Precise measurement of thickness, length, and width

Chemical Composition and Mechanical Property Analysis: Third-party testing reports

Surface Inspection: Visual and microscopic inspection for defects

Ultrasonic Testing: Detection of internal defects
