35ml R60702 Zirconium Laboratory Crucible (2mm Wall Thickness)

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 Introduction

This 35ml laboratory zirconium crucible, featuring a 2mm wall thickness, is manufactured from high-purity industrial-grade zirconium (Grade R60702) via integral mechanical machining. Compared to standard thin-walled crucibles, the reinforced 2mm wall design significantly enhances mechanical strength and thermal shock resistance, making it specifically suited for rigorous high-temperature alkali fusion pretreatment experiments.

Grades: Zr702, Zr705, R60001, R60901

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

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

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.

II. Key Features and Advantages
Superior Resistance to Deformation: The 2mm thick-walled structure maintains excellent creep resistance during sintering or melting processes in high-temperature muffle furnaces (900°C to 1200°C), ensuring the vessel does not easily suffer from bottom bulging or sidewall collapse during prolonged use.
Excellent Resistance to Alkali Corrosion: It exhibits exceptional chemical stability against strong alkaline fluxes—such as sodium peroxide ($\text{Na}_2\text{O}_2$), sodium carbonate, and sodium hydroxide—as well as alkali metal oxides, making it highly resistant to corrosion.
Extended Service Life: The thickened metal layer significantly increases the safety margin against oxidation and chemical degradation, effectively prolonging the overall service life under conditions of high-frequency and high-load experimentation.

High Purity and Contamination-Free: At high temperatures, a dense zirconium dioxide ($\text{ZrO}_2$) passivation layer spontaneously forms on the surface; this layer is chemically inert, preventing the introduction of impurity interference during the analysis of complex samples.

III. Key Application Scenarios

Analysis of refractory ores and geological samples: Widely used for the sodium peroxide alkaline fusion decomposition of chromite, ilmenite, silicates, and refractory materials.

Synthesis of specialty materials: Suitable for high-temperature inorganic salt melting, catalyst preparation, and the laboratory-scale development of high-end chemical raw materials.

IV. Precautions for Use and Maintenance

Strictly avoid strong acids: Zirconium is extremely sensitive to hydrofluoric acid (HF), as well as hot concentrated sulfuric acid and concentrated hydrochloric acid; do not use such acids for cleaning or containment.

Prevent contamination by low-melting-point metals: At high temperatures, metals such as lead, zinc, tin, and copper react with zirconium to form low-melting-point alloys, which can cause perforation of the vessel walls; strictly prohibit the melting of samples containing these impurities.

Follow proper heating and cooling procedures: Heating should be performed in a temperature-controlled muffle furnace, followed by natural cooling; rapid quenching with water or forced air cooling is strictly prohibited.
