The invention discloses 95 high alumina ceramic which comprises the following components in percentage by mass: 93-95% of alumina, 3-5% of modified silicon carbide whisker, 1-2% of magnesium oxide and 1-2% of silicon dioxide. The silicon carbide whisker is modified by using the silane coupling agent to improve the dispersity of the silicon carbide whisker, then nickel-based modification is performed on the basis, and the mechanical strength, toughness and wear resistance of the 95 high alumina ceramic are integrally improved through two times of modification.
本发明公开了一种95高氧化铝陶瓷，包括以下组分，以质量百分数计，氧化铝93％‑95％、改性碳化硅晶须3‑5％、氧化镁1‑2％、二氧化硅1‑2％。本发明通过在碳化硅晶须使用硅烷偶联剂进行改性提高其分散性，再在此基础上进行镍基改性，通过两次改性整体上提高了95高氧化铝陶瓷的机械强度、韧性与耐磨性。
