The invention discloses a crescent-shaped and deformed ceramic microparticle, its preparation method, application and preparation device. The inner phase fluid is introduced into the outer phase fluid in the outer phase glass tube through an inner phase glass tube; The inner phase fluid forms water-in-oil emulsion droplets at the outlet of the inner phase glass tube, and the droplets flow through the cross-exposure area of the two beams of ultraviolet light with the liquid flow; the inner phase fluid droplets are collected by exposure and solidification, and then cleaned, After drying, cross-linking, ageing, and sintering, crescent-shaped and deformed ceramic microparticles are obtained. Based on the microfluidic chip, the crescent shape and its deformed microparticle green body prepared by oil-water two-phase have the characteristics of precise and controllable shape and uniform size, which provides a basis for its mass and stable production. |
