Study of the Influence of Nano Component Optimization on Strength of Ceramic Bond

以R_2O-RO-B_2O_3-Al_2O_3-SiO_2为基础陶瓷结合剂,在不改变原有结合剂配方的组成前提下,用纳米Al_2O_3、纳米SiO_2、纳米CaO部分取代原有配方中的Al_2O_3,SiO_2,CaO成分,运用正交实验的实验方法,研究了纳米组分优化对陶瓷结合剂抗折强度的影响。试验结果表明:纳米组分优化对结合剂抗折强度影响显著,其中当部分替换纳米Al_2O_3含量为2%、纳米CaO含量为1%、纳米SiO_2含量为4%时,优化配方抗折强度最大,其抗折强度达到104.24MPa。

Influence of nano component optimization on bending strength of ceramic bond has been studied by orthogonal experiment. In the experiment, the composition of the original formula remains the same, and R_2O—RO-B_2O_3—Al_2O_3—SiO_2 has been used as basic Ceramic bond as constituents of Al_2O_3,SiO_2,CaO been partially substituted by nano—Al_2O_3,nano—SiO_2 and nano-CaO. Result shows that nano component optimization has significant influence on bending strength of ceramic bond. The bending strength of the optimized formula reaches its maximum value（104. 24MPa） when the contents of nano—Al_2O_3,nano—CaO and nano—SiO_2 are respectively 2%,1% and 4%.
