The higher the purity of alumina ceramics-95%, the greater their mechanical strength, corrosion Modstand, electrical insulation, and thermal stability.
Det er et af de mest udbredte og velkendte præcisionskeramiske materialer. Det udviser fremragende mekanisk styrke, elektriske isoleringsegenskaber, lavt dielektrisk tab, termisk ledningsevne og høj modstand mod varme, slid og korrosion. Fordelene ved aluminiumoxidkeramik og deres anvendelsesindustrier er skitseret nedenfor:
