摘要

采用Al2(SO4)3脱硫法制备了纳米拟薄水铝石，研究了其对商品陶瓷的补强性能。断裂试样的SEM分析表明，添加的伪薄水铝石前驱体在陶瓷玻璃相中产生了纳米原生莫来石相，从而限制和阻止了晶间裂纹的扩展。陶瓷的断裂模量(108 MPa)比未添加伪薄水铝石的试样增加了两倍。根据热测量数据显示，伪薄水铝石也会导致陶瓷陶瓷体在1250°C时致密化。

Increasing Bending Strength of Porcelain Stoneware via Pseudoboehmite Additions

Pseudoboehmite nanoparticles synthesized through the desulfation of Al2(SO4)3 were used to investigate the reinforcement of commercial porcelain stoneware. Fractured specimens investigated by SEM suggest that the added pseudoboehmite precursor generated a nanometric primary mullite phase dispersed in the porcelain glassy phase that limited and stopped the intergranular crack propagation. The porcelain modulus of rupture increased twice the value of the modulus of rupture (108 MPa) as compared with that samples without pseudoboehmite additions. Pseudoboehmite also led to increased densification of porcelain stoneware bodies up to 1250°C as shown by thermodilatometry data.
