Fabrication of nacre-like inorganic materials with innovative properties

在胶体过滤过程中，利用强磁场对制备的高温稳定的MAX相陶瓷颗粒进行排列，然后采用火花等离子烧结、毫波烧结等新型烧结技术对干燥后的青坯进行致密化处理。织构的MAX相陶瓷（Nb4AlC3、Ti3Si(Al)C2、Ti2AlN）在纳米至微米尺度上均呈壳状结构，具有较高的抗弯强度和断裂韧性。

Strong magnetic field was applied to align particles synthesized of MAX phase ceramics, those are stable at high temperatures, during colloidal filtration and then densified the dried green bodies by novel sintering techniques, such as spark plasma sintering, mili-wave sintering. The textured MAX phase ceramics (Nb4AlC3, Ti3Si(Al)C2,Ti2AlN) possessed a shell-like microstructure configuration from the nano- scale to the milli- scale, which endowed them with a high flexural strength and the augmented fracture toughness.
