Preparing Porous Si-based Ceramic Core Using Thermosetting Silicon Resin Injection Method

doi:10.15541/jim20140280

Abstract

Abstract:

The porous Si-based ceramic core was prepared using injection method, where quartz glass powders were used as original materials and thermosetting silicon resin was used as plasticizer. The effect of sintering temperature and holding time on the properties of the samples were examined. It was found that the process of devitrification was accelerated with the increase of sintering temperature while the glass phase transforms into cristobalite gradually. When sintering temperature was at 1250℃, the amount of cristobalite increased with the extension of holding time. Linear shrinkage rate and weight loss of the samples slightly increased with the increase of sintering temperature. But the holding time showed less effect on linear shrinkage rate and weight loss of the samples. In fact, the weight loss of the sample was mainly caused by decomposition of silicon resin. The sample sintered at 1250℃ for 10 h showed linear shrinkage of 0.93%, the porosity of 32.8% and bending strength of 9.08 MPa.

Key words: porous, silicon resin, ceramic core, linear shrinkage rate, bending strength, porosity
