Filled Aluminosilicate of Dendrimer Morphology Used as Low Temperature Cofired Ceramic in LED Devices and Spacecraft Control Systems

摘要

Sol-gel synthesis of filled aluminosilicates with macromolecules having a dendrimer morphology (Mcalcud≈ 480000) was developed. The software package Gaussian B3LYP/6-31G(d) was used to assess the possibleudmechanism by which nuclei of dendrimer molecules are created, with the subsequent generation of crownsudof branched ensembles capable of accommodating up to 80 wt % nano-AlOOH as a filler. The data furnishedudby transmission electron microscopy of the samples are in agreement with the suggested mechanismudof generation and growth of dendrimers. The main results were obtained on fi lledaluminosilicateudsamples that contain 80 wt % nano-AlOOH and exhibit a high wear resistance in tribological tests.
