45ml pure zirconium crucible for scientific research laboratory99.5%

1. Commonly Used Materials

Execution Standards: Zirconium Plate ASTM B551, Zirconium Rod Billet ASTM B550

2. Key Physical and Chemical Parameters

Melting Point: 1852℃, ≤900℃ in normal air use, up to 1200℃+ in inert atmosphere;

Density: 6.51g/cm³, low thermal expansion, resistant to thermal shock, not easily cracked;

Corrosion Resistance: Resistant to strong alkalis, concentrated sulfuric acid, concentrated phosphoric acid, and various alkaline fluxes far superior to nickel crucibles; not resistant to hydrofluoric acid (HF) and fluoride molten salts;

Forming: Seamless spinning integral forming, polished inner wall; Specifications: Laboratory 5~100mL, industrial non-standard 100~5000mL, with matching zirconium crucible lid.

3. Product Advantages: Alkali melting can replace platinum crucibles, costing only 1/8 to 1/10 of platinum crucibles, with no heavy metal impurities precipitated, and no contamination of sample testing data; High-temperature sodium peroxide melting is less prone to oxidation and scaling, and compared to nickel crucibles, it has a higher upper temperature limit and longer lifespan; Excellent inertness, it does not chemically react with molten titanium, zirconium, or precious metals.

II. Applications Across All Fields

(I) Physicochemical Laboratories (Core Uses)
**Strong Alkali System Sample Melting and Digestion (Upgraded Replacement for Nickel Crucibles)**
**Compatible Fluxes:** NaOH, KOH, Na₂O₂, Na₂CO₃, Lithium Metaborate High-Temperature Melting (600~850℃)
**Pretreatment of Soil, Ores, Rare Earth Minerals, Silicates, Refractory Materials, and Cement Raw Materials (ICP/Atomic Absorption Spectroscopy);**
**Environmental Testing, Third-Party Testing, and Geological Exploration Sample Full-Element Alkali Melting Decomposition (National Standard HJ974 Soil Testing Standard Replacement for Platinum Dishes).**

**High-Temperature Solid-Phase Synthesis and Precipitation of Various Salts (High-Temperature Calcination).**

(II) Precious Metal/Non-Ferrous Metal Smelting
**Vacuum Melting and Fire Assay Analysis of Small Samples of Precious Metals such as Gold, Silver, Platinum, and Palladium;**
**Small-Batch Smelting of Titanium Alloys, Zirconium Alloys, and Rare Metals, Preventing Crucible Impurities from Penetrating into Raw Materials During the Melting Process.** (III) Chemical and New Materials Industries: High-temperature strong alkali reaction vessels and small-scale crucibles for fine chemicals; high-temperature melting preparation of inorganic salts; high-temperature calcination synthesis of lithium battery powders, rare earth oxides, and ceramic powders; high-temperature reaction vessels for special reagents under corrosive conditions.
