Al2O3-La2O3-Y2O3-MgO ceramic and manufacturing method thereof

摘要

And a manufacturing method thereof (including a glass-ceramic glass, and crystalline ceramic,) Al ₂ O ₃ -La ₂ O ₃ -Y ₂ O ₃ -MgO ceramic. It can be a thin coating of glass beads, the article (eg, plates), fibers, and particles, produced, or formed, to convert them, the ceramics according to the present invention. For example, particles and fibers, is useful as a reinforcing material composite thermal insulator, or fillers (eg, polymer matrix composite ceramic, or metal,) in. For example, thin coatings can be as protective coatings in applications involving wear, and it is useful for thermal management. Some embodiments of the ceramic particles according to the invention may be particularly useful as abrasive particles.
