The results show that the glass-ceramics with fibroid structure is produced after definite heat treatment, the main crystallization phase is hedenbergite and anorthite is the minor crystallization phase. The optimal process of heat treatment shows as follows: the nucleation temperature is 850 ℃ and hold time is 100 min, and the crystallization temperature is 980 ℃ and hold time is 80 min. With increasing heat treatment temperature, the FT-IR absorption bands appear obvious split, the aluminum-oxide polyhedron in the glass network changes from [AlO4] to [AlO6]. The titanium ion in the glass network gradually transforms to the 6-coordinated, moreover forms minicrystal of MgTi2O5 and Fe2TiO4 which provides the position of heterogeneous nucleation for the growth of crystal.

结果表明：在一定的热处理条件下可以以基础玻璃制备出主晶相为钙铁透辉石，次晶相为钙长石的纤维状结构的微晶玻璃；最佳的热处理工艺为：850 ℃核化100 min，980 ℃晶化80 min；随着热处理温度的升高，红外吸收带发生明显的分裂；玻璃结构中的[AlO4]向[AlO6]转化；网络结构中的钛离子逐渐转变为六配位，形成微晶相——钛酸镁和钛铁晶石，为晶体的生长提供非均匀形核位置。

The results show that, Main crystallization phase of glass ceramic was hedenbergite, and the minor crystallization phases were augite and hypersthene. With increasing boron mud addition, the amount and the size of crystallization phases both gradually increased, the configure of crystallization phases transformed from the branch, the ball, to the block. The transformation from the branch to the ball could improve the properties of glass ceramic, and the transformation from the ball to the block could worsen the properties of glass ceramic.

结果表明：矿渣微晶玻璃的主析晶相为钙铁辉石，次晶相为普通辉石和紫苏辉石；随着硼泥配入量的增加，矿渣微晶玻璃中晶体的析出量和尺寸均逐渐增加，晶体形态由枝晶向球晶及块状晶体过渡；枝晶向球晶转变可以明显改善矿渣微晶玻璃的性能，而球晶向块状晶体的转变则恶化了微晶玻璃的性能。

Otherwise, the hedenbergite formed at 1 100 ℃ in the heating process is the main reason for lowering the ash melting temperature.

低灰熔融煤灰在加热过程中，1 100 ℃时少量铁钙辉石的生成起到了降低煤灰熔融的作用。
