説明
Magnesia-Alumina Spinel Crucible
Magnesia-Alumina spinel crucibles are manufactured using periclase (MgO) and magnesium-alumina spinel (MgAl₂O₄) as the main refractory minerals, with the addition of high-quality mineralizers, through high-pressure molding and high-temperature sintering processes. The product has a dense crystal structure and strong particle bonding, exhibiting excellent high-temperature resistance, high-temperature mechanical strength, and thermal shock resistance.The bulk density of magnesium-alumina spinel crucibles is generally ≥3.2 g/cm³, and the maximum service temperature can reach 1750℃. As it is an alkaline refractory material, the product has extremely strong corrosion resistance to alkaline melts and alkaline environments.
製品の特徴
- Alkaline Refractory Material with Stable Spinel Structure
The main materials are periclase and spinel, which are closely combined with mineralizing agents, high-pressure molding, and high-temperature sintering. The spinel structure gives excellent thermal stability and chemical stability, and it is an alkaline refractory material.
- High Strength and Excellent Thermal Shock Resistance
With a bulk density >3.2 g/cm³, spinel exhibits a dense structure and high strength. Its low thermal expansion and excellent thermal shock resistance make it suitable for batch processes involving frequent temperature increases and decreases, as it does not crack under rapid temperature changes.
- Ultra-High Temperature Performance, Long-Term Use at 1750℃
With a maximum operating temperature of 1750℃, it can be used stably at high temperatures for extended periods. It does not deform or soften at high temperatures, making it suitable for alkaline smelting and sintering processes requiring high refractoriness.
- Excellent resistance to alkaline corrosion
It exhibits extremely high corrosion resistance in alkaline environments, and can withstand long-term erosion by alkaline melts, alkaline fluxes (such as sodium carbonate, borax, etc.), and alkaline slag. It does not readily react with alkaline materials, ensuring product purity.
