一种纤维增韧YSZ复合粉体的制备方法
摘要：
本发明公开了一种纤维增韧YSZ复合粉体的制备方法，其制备方法为：将浓度为2.0wt％～8.0wt.％掺有分散剂的PVA溶液与YSZ和纤维混合形成均一体系，用不同种类的纤维与YSZ混合制得的固含量为30wt.％～70wt.％的浆料，并通过喷雾干燥法制得YSZ颗粒充分包裹纤维的复合粉体。制备得到的纤维增韧YSZ复合粉体粒度均匀，流动性好，松装密度相对较高。
摘要（英）：

The invention discloses a preparation method of fiber toughening YSZ composite powder. The preparation method includes mixing the PVA solution with the concentration of 2.0 wt% to 8.0 wt% mixing a dispersant, YSZ and fiber to form a uniform system, mixing the different kinds of fiber and YSZ to form a slurry with the solid content of 30 wt% to 70 wt%, and preparing a composite powder which is a YSZ particle fully wrapped fiber by using a spray-drying process. The prepared fiber toughening YSZ composite powder has uniform granularity, good fluidity and high apparent density.
