원심테르밋반응에 의한 파이프 세라믹층 형성 - 미세조직 변화

Preparation of ceramic lined pipe by centrifugal-thermit process - Micro-structure of ceramic layer

초록

Microstructures of the lined ceramic layers were surveyed in the case of SiO2 usage as an additive. The use has induced in the formation of amorphous silicate compounds, mullite(2FeO·SiO2) and fayalite (3Al2O3·2SiO2), for the ceramic layers. Which contributes the increase of keeping time as the liquid phase, and improves the densification for the layer in the course of cooling procedure. As the results of composite analysis in the layer after heat treatment at 1,150 ℃ and 1,350 ℃, it can be proposed that a mechanism of solidification and densification progresses through four steps for the ceramic layer formation
