摘要

由铝土矿和长石制备的低密度陶瓷支撑剂的主要晶相为粒状刚玉和须状莫来石。莫来石晶须彼此环环相扣，堆积在孔隙中。孔隙内莫来石晶须长径比高，可大大提高断裂韧性。支撑剂的主要增韧机制是莫来石晶须的裂缝分岔挠曲和拉出搭桥作用。

Toughening effect of mullite whisker within low-density ceramic proppants

Main crystal phases of low-density ceramic proppants prepared by bauxite and feldspar are granular corundum and whisker-shaped mullite. Mullite whiskers are interlocked with one another and piled up inside the pores. High aspect ratio of mullite whiskers inside the pores can greatly enhance the fracture toughness. The dominant toughening mechanism for the proppants is attributed to crack bifurcation and deflection and pulling out and bridging effect of mullite whiskers.
