MgO Ceramic Crucible
Made from high-purity magnesium oxide (MgO) through precision forming and high-temperature sintering, Meetcera MgO crucibles feature a fully fired, high-density, fine-grained microstructure. They are ideal for ultra-high temperature processing of metals, slags, and superconductor compounds. MgO ceramics provide a superior alternative to alumina crucibles due to their better chemical resistance and inertness, especially in alkaline or extreme-temperature environments.
Key Features & Benefits
- Ultra-High Temperature Resistance: Maximum service temperature up to 1800°C
- Excellent Corrosion Resistance: Highly resistant to alkaline melts, metal slags, precious metals, and radioactive materials; chemically inert
- High Purity: MgO content 99%, minimizing sample contamination
- High-Density Microstructure: Fully fired for low porosity and superior durability
- Strong Thermal Stability: Excellent thermal shock resistance and uniform heating
- Superior Electrical Insulation: High volume resistivity at elevated temperatures
Available Shapes:
Conical and arc, cylindrical, oval, square and rectangular shapes, plus many special shapes. Capacities range from 5 ml to 2000 ml. Larger capacities and irregular shapes are available upon request.
Main Applications:
- Ultra-high temperature melting of metals, slags, and superconductor compounds
- Metalworking and molten glass
- Precious metals melting (platinum, rhodium, iridium, etc.)
- Non-ferrous metals & alloys (copper, aluminum, zinc, nickel, etc.)
- Gemstone purification in the jewelry industry
- High-temperature chemical experiments, rapid thermal cycling, molten salt electrolysis
- Semiconductor, electronics, vacuum furnace processes, and laboratory analysis
Usage Notes:
Most applications such as metalworking, molten glass, rapid thermal cycling, and gemstone purification require impermeable ceramics. Porous forms can also be produced to order.
- Avoid prolonged exposure to strong acids
- Heat and cool gradually to maximize service life
- Allow natural cooling after use; avoid sudden thermal shock
