A 35ml inclined-wall zircon crucible was used in the study.

Pure Zirconium Crucible (Industrial Pure Zirconium Zr ≥ 99%)

Product Introduction
Material: Manufactured using industrial pure zirconium Zr1, Zr2 (Chinese national standard) or R60702 (Zr702, American standard).

Purity: 99.0% ~ 99.95%, high-end products can reach 99.97%.

Core Performance:
High Melting Point: 1852℃, normal safe operating temperature <1600℃.

Excellent Corrosion Resistance: Forms a dense oxide film on the surface, resistant to most acids, alkalis, and molten metal corrosion.

Chemical Inertness: Does not react with reactive metals such as titanium, tantalum, niobium, and rare earth elements at high temperatures, ensuring high material purity.

Thermal Shock Resistance: Low coefficient of thermal expansion, resists sudden temperature changes, and is not prone to cracking.

II. Nuclear-Grade Zirconium Crucible (Nuclear-Grade Zirconium Alloy)

Product Introduction
Material: Special nuclear-grade zirconium alloy (mainly Zr-4 alloy, Zircaloy-2, M5, etc.), strictly adhering to nuclear power standards (such as ASTM R60804).

Core Characteristics (Distinguishing from Pure Zirconium):
Extremely Low Neutron Absorption Cross Section: Does not interfere with nuclear reactions, a key characteristic in the nuclear industry.

Ultra-Purity Control: Impurities (especially neutron absorbers such as Hf, B, and Cd) <50ppm.

High-Temperature Water/Steam Corrosion Resistance: Optimized for the high-temperature, high-pressure water environment of reactors.

Radiation Stability: Structurally stable and non-embrittled under long-term irradiation.

III. Comparison of Core Differences

Summary

Pure Zirconium Crucibles: General-purpose high-temperature, high-purity containers, emphasizing corrosion resistance, purity, and thermal shock resistance, covering high-end metallurgy and scientific research.

Nuclear-grade Zirconium Crucibles: Dedicated to the nuclear industry, their core value lies in low neutron absorption, ultrapurity, and radiation resistance, serving applications in fuel, experimental, and waste disposal.
