High-purity zirconium crucibles (99.7%) for use in scientific research laboratories.

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.

Zirconium crucibles (mainly divided into metallic zirconium crucibles and zirconium oxide (ZrO₂) crucibles) are top-tier crucibles for high-temperature, high-purity, and highly corrosive environments. Their core characteristics include ultra-high temperature resistance, chemical inertness, thermal shock resistance, high strength, and low pollution. They are particularly suitable for the melting and preparation of rare/precious metals, special alloys, and semiconductor materials. They are generally used for melting in scientific research laboratories.

High-purity zirconium crucible specifications

Zircon crucible sample display

Grades: Zr702, Zr705, R60001, R60901

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

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

Surface finish: Bright/Polished

Wall thickness: 1 mm, 2 mm, or customizable

Service life: Crucibles with 2 mm wall thickness offer a longer service life than thin-walled versions and can be reused over 100 times
 Highly resistant to most reagents
 Soluble in hydrofluoric acid
 Withstands temperatures up to 900°C
Low-form crucibles are made of zirconium alloy with a thickness of 0.89 mm. Oxidation begins upon prolonged exposure to air at temperatures above 550°C. Not recommended for use with fluoroboric acid or fluorosilicic acid. Suitable for high-temperature fusion in the reducing flame of a burner.

 Zirconium Metal Crucible (High Purity Zr, 99%+)
Melting Point: 1852℃, Long-term Safe Use ≤1600℃
Chemical Properties: Extremely strong chemical inertness, almost no reaction with active/rare metal melts such as Ti, Ta, Nb, Zr, and U.
Resistant to most acids and alkalis, and resistant to molten metal wetting (non-stick, non-contaminating).
Thermal Properties: Low thermal conductivity, small coefficient of expansion → excellent thermal shock resistance (not easily cracked by rapid heating and cooling).
Mechanical Properties: High strength, good toughness, erosion resistance, and long service life (approximately 3 times that of graphite crucibles).
Purity: Impurities at the ppm level, suitable for ultra-high purity materials (aerospace titanium alloys, nuclear materials).
