It has been discovered and demonstrated, via scanning electron microscope examination on 6 samples of broken glasses, that one important cause for the spontaneous breakage in tempered glass occurs as a result of the single-phase polycrystalline silicon particles, rather than simply the nickel sulfide (NiS) particles that are commonly recognized to be the main cause for the spontaneous breakage.
通过对 6 块玻璃自爆残片的电镜观察和成分分析,发现并证明了引起钢化玻璃自爆的主要原因不仅仅是传统认识中的硫化镍(NiS)微粒,很多情况是由单质硅微粒引起的。

硅质隔热耐火砖
silica insulating refractory brick
guizhi gere naihuozhuan硅质隔热耐火砖(siliea insulating:efraetorybrick)以硅石为主要原料制成的，510:含量不小于91%的隔热衬火制品。硅质隔热耐火砖除具有隔热保温性能外，在很大程度上保持硅砖的特性，荷重软化开始温度高，在加热过程中，体积略有膨胀，使窑炉的整体性增强。 制造硅质隔热耐火砖采用经过细粉碎的硅石为原料，加入部分废硅砖或废硅质隔热耐火砖粉、矿化剂和烧尽加入物等。按一定配比在混练机中加水混合成泥料，经机械或手工成型，砖坯干燥后残余水分小于。.5%方可装窑。为防止因510:多晶转变发生剧烈体积膨胀，引起制品产生裂纹，烧成时要求比较缓慢的升降温速度。 中国冶金工业部行业标准YB386一63规定的工业护用硅质隔热衬火砖QG一1.2牌号产品性能:体积密度不大于1.29/cm，，常温衬压强度不小于3.43MPa，衬火度不低于16700C，0.o98MPa下荷重软化开始温度不小于1560℃，510:含量不小于91%。 该产品适用于砌筑工作温度不超过155。℃，不与高温熔融物料直接接触和不直接受到侵蚀性气体作用的工业炉护衬或用于隔热层。 硅质隔热耐火砖由于硅石粉尘对人体危害大，工艺过程比粘土质和高铝质隔热耐火砖复杂，在隔热衬火材转总产量中所占比重很小。 (黄佛海于文涛)
