摘要
Abstract
High properties transparent Si3N4-BN-SiO2 ceramic composites with Si-B-O-N based were prepared by gas pressure sintering(GPS). The effects of BN and nano-SiO2 contents on the mechanic and dielectric properties of the composites were described. The microstructure characteristic and reinforced mechanism of the composites were investigated. The results show that it can be obtained a series of Si-B-O-N ceramic transparent materials by controlling the content of raw materials and technological parameter. The bending strength of composites is from 74.7MPa to 174.83MPa and the dielectric constant is from 3.5 to 4.2 and the dielectric dissipation is 0.5-4.5 × 10-3.关键词
