影響は避けられない、このため、材料の脆性化が起こる
。As one of the improvement measures, the surfaces of fibers and particles are coated with Cu or Ni by electroplating or electroless plating in order to control the wettability and interfacial reaction with the matrix. However, since it is usually carried out in an aqueous solution system, the influence of moisture cannot be avoided, which causes the material to become brittle.

した後、沈澱物を冷凍乾燥器で乾燥させた。"Example" Example 1 10 grams of ZrO28% Y2O3 powder was suspended in 200 ml of anhydrous methanol in a beaker, and while stirring well with a magnetic stirrer, it was placed in another beaker in advance at 0°C in anhydrous methanol. Ni adjusted to a concentration of 1 molar
When the metal ion solution is dropped from the buret and the entire particle becomes almost black, dropping is stopped and stirring is continued for a while. After solid-liquid separation using a centrifuge, the precipitate was dried using a freeze dryer.
