Refractory for siliconizing furnaces
The purpose of the present invention is to provide a refractory for siliconizing furnaces, which is suppressed in change of properties and embrittlement, and which has a long service life. A refractory for siliconizing furnaces, which contains 35% by mass or more in total of one or more substances that are selected from among silicon oxides, silicon nitrides and silicon oxynitrides and 0.05% by mass or less in total of alkali metals, while having a porosity of 25% by volume or less and a compressive strength of 5 MPa or more.
本发明的目的在于提供一种变质、脆化少，寿命长的渗硅处理炉用耐火物。所述渗硅处理炉用耐火物含有合计35质量％以上的选自硅的氧化物、硅的氮化物和硅的氧氮化物中的1种或2种以上和合计0.05质量％以下的碱金属，并且，气孔率为25体积％以下，压缩强度为5MPa以上。
