Abstract
The degradation of refractories can be caused by erosion, friction of abrasive particles, as well as by corrosion by molten slag in the gasification reactors. There was little knowledge about the erosion of refractories so far. The castable refractories of which the maximum applying temperature of 1300 and $1500^{\circ}C$ were abraded using SiC particles varying the incidence angles. It was revealed that the maximum abrasion was occurred at the incidence angle of $60{\sim}75^{\circ}$ not at $90^{\circ}$ and thought that the porosity of the refractories was the principle factor.
