Magnesium Oxide Crucible Description
A magnesium oxide crucible is a high-performance ceramic container crafted from premium-grade magnesium oxide, specifically engineered for demanding high-temperature applications. It excels in environments where extreme heat, thermal shock resistance, and chemical inertness are paramount. With a melting point exceeding 2800°C, it reliably operates in continuous service at temperatures up to 2200°C, maintaining structural integrity in both oxidizing and inert atmospheres. The crucible demonstrates notable resistance to basic slags and molten metals, particularly reactive and refractory metals, while its high purity minimizes contamination risks in sensitive processes. Commonly utilized in advanced metallurgy, nuclear fuel processing, crystal growth, and the synthesis of high-purity ceramics, its design can be customized to meet specific geometric and functional requirements, making it an indispensable tool in research and industrial settings that operate at the forefront of materials science and high-temperature technology.

FAQ
What is a Magnesium Oxide Crucible? What are its advantages in high-temperature applications?
It is a high-temperature container made from high-purity magnesium oxide ceramic. Key advantages include an extremely high melting point (>2800°C), excellent thermal shock resistance, and corrosion resistance to basic slags/reactive metals.
What is the maximum operating temperature of a Magnesium Oxide Crucible?
Under inert or oxidizing atmospheres, it can operate continuously up to 2200°C, with short-term tolerance for higher temperatures. The actual temperature depends on specific conditions.
Which metals are suitable for melting in a Magnesium Oxide Crucible?
It is ideal for high-melting-point metals (e.g., platinum, rhodium) and reactive metals (e.g., uranium, thorium), but not recommended for strongly acidic melts or reactive low-melting-point metals like lithium/aluminum.
What is the difference between MgO and Alumina (Al₂O₃) Crucibles?
MgO crucibles have a higher melting point (>2800°C vs. ~2050°C) and better alkali resistance, but lower mechanical strength than alumina. Alumina is more versatile and cost-effective.
Do Magnesium Oxide Crucibles contaminate molten materials?
High-purity MgO crucibles (≥99% purity) pose minimal contamination risk, making them suitable for high-purity processes like crystal growth or alloy synthesis.
