Thin-walled zircon crucibles for metallurgical applications 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.

I. 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.

Thin-walled zirconium crucibles are lightweight, high-temperature resistant containers made of high-purity metallic zirconium (Zr≥99.2%, R60702 grade) with a wall thickness of 0.6–2 mm. Their core advantages are rapid heating, accurate temperature control, and extremely low sample contamination. They are suitable for micro-volume/high-precision high-temperature experiments and are a cost-effective alternative to platinum crucibles.

Grades: Zr702, Zr705, R60001, R60901

Capacity: 5-50ml (Custom sizes available upon request)

Types: Short-walled zircon crucibles, zircon crucibles with flanged edges, straight-walled zircon crucibles, sloping-walled zircon crucibles, cylindrical zircon crucibles

Surface: Glossy

Wall Thickness: 0.6mm, 1mm, 2mm or customizable

Rapid Thermal Response: With a wall thickness of 0.6–2mm, it heats up 30%–50% faster than conventional zircon crucibles (3–10mm), offering excellent thermal uniformity and temperature control accuracy up to ±5℃.

I. Core Features (Thin-Wall Exclusive Advantages)

Rapid Thermal Response: With a wall thickness of 0.6–2 mm, it heats up 30%–50% faster than conventional zirconium crucibles (3–10 mm), offering excellent thermal uniformity and temperature control accuracy up to ±5℃.

High Purity and No Contamination: Material impurities <0.8%, smooth surface (Ra≤0.2μm), no glaze layer, and no exudation, suitable for trace element analysis and high-purity sample preparation.

Lightweight and Thermally Shock Resistant: Density 6.52 g/cm³, weighing only 1/3 of a ceramic crucible of the same volume; low coefficient of thermal expansion, capable of withstanding temperature fluctuations of 1000℃/min, and resistant to cracking after repeated use.

Strong Corrosion Resistance: Resistant to concentrated acids and alkalis, molten alkali metals, sodium peroxide, etc., and does not react with reactive substances such as silicon, aluminum, and titanium, making it suitable for harsh chemical environments.

II. Key Parameters

Material: High-purity zirconium Zr≥99.2% (R60702), no alloy doping.

Operating Temperature: Long-term ≤1600℃, short-term ≤1800℃ (inert/vacuum); **≤1200℃ in air** Anti-oxidation.

Specifications: Diameter 10–50mm, Height 20–80mm, Wall Thickness 0.6–2mm; With/Without cap, Tolerance ±0.1mm.

Surface: Mirror polished, easy to clean, no material residue.

III. Typical Application Scenarios

Chemical Analysis (Alkali Fusion Method)

Ore/Geological Samples: Sodium peroxide melting digestion (e.g., chromite, ilmenite, silicates).

Trace Element Detection: Atomic absorption, ICP-MS sample pretreatment, no heavy metal contamination.

Materials Science (Trace Synthesis)

High-Temperature Sintering: Small-batch preparation of nano-ceramics, oxide powders (e.g., ZrO₂, Al₂O₃).

Active Metal Smelting: High-purity small ingots (10–50g) of titanium, zirconium, niobium, etc., no carbon contamination.

Semiconductor/Electronics: Synthesis of high-purity oxides and target precursors; low impurities and thermal uniformity ensure batch consistency.

Nuclear Industry/Specialized R&D: Processing of radioactive samples and nuclear-grade materials; low neutron absorption and chemical inertness.
