15-50mlZircon crucible

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.

702 Zirconium Crucible (Zr702/HZr702, ASTM R60702) is a high-performance, high-temperature resistant, and corrosion-resistant container made of industrial pure zirconium with a zirconium content ≥99.2% and extremely low impurities.

Core Parameters

Grade: Zr702 (R60702)

Purity: ≥99.4%

Density: 6.51 g/cm³

Melting Point: 1852℃, long-term usable temperature ≤1200℃

Process: Forging/spinning + precision machining, seamless one-piece or with lid

Specifications: Volume 10 mL – several liters, wall thickness 0.5–5 mm, customizable

Key Characteristics

Strong Corrosion Resistance: Forms a dense oxide film at room temperature, resistant to sulfuric acid, hydrochloric acid, strong alkalis, and molten salts, superior to titanium and stainless steel, approaching tantalum.

High Temperature Stability: Maintains good strength at high temperatures, resistant to thermal shock, not prone to cracking, and has a lifespan approximately 3 times longer than graphite crucibles.

Chemical Inertness: Does not contaminate high-purity materials, suitable for the preparation of high-purity metals and semiconductor materials.

Low Neutron Absorption: Suitable for nuclear fuel processing in the nuclear industry.

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.

II. Main Application Areas

High-Temperature Metallurgy / Vacuum Melting
Vacuum melting and casting of reactive/high-purity metals such as titanium, aluminum, niobium, and tantalum.

Melting of precious metals (gold, silver, platinum) and rare earth alloys, reducing impurities.

Preparation of high-temperature alloys and precision castings, avoiding carbon contamination.

Semiconductor and Crystal Growth
Single crystal growth crucibles for SiC, sapphire, YAG, etc. (e.g., Czochralski method, pulling method).

Synthesis of high-purity compound semiconductor materials, ensuring purity.

Chemical and Corrosive Environments
Strong acid/strong alkali reaction vessels, evaporating dishes, melting vessels.

Handling corrosive materials in petrochemical and fine chemical industries.

Nuclear Industry
Nuclear fuel (uranium, plutonium) handling and storage containers, neutron-transparent, corrosion-resistant.

Research and Laboratories
Temperature analysis (TGA/DSC), high-temperature sintering, material synthesis crucibles.

Geological, metallurgical, and materials science experiments, chemically resistant, reusable.

Other: Aerospace: High-temperature component manufacturing; Photovoltaics: Silicon material purification and crystal growth auxiliary containers
