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。
