具有三维网络结构的LiTi 2（PO 4）3（LTP）和具有二维层状结构的Ti（HPO 4）2·2 H2O（TP）是典型的磷酸盐晶体，具有不同的性能。利用LTP在50°C的酸性溶液中转变为TP的新发现，制备了具有LTP和TP晶体骨架的一体化微孔微晶玻璃。以LiTi_2（PO_4）_3·Ca_3（PO_4）_2准二元系玻璃为原料，通过控制晶化和酸处理制备了多孔微晶玻璃。获得了具有直径为30 nm和50 nm的连续孔的块状样品，而没有严重的开裂或变形。报道了合成路线和步骤，并对其微观结构和可能的改进进行了讨论。
LiTi2(PO4)3(LTP) with a three-dimensional network structure and Ti(HPO4)2·2H2O (TP) with a two-dimensional layered structure are typical phosphate crystals with different properties. Integrated microporous glass-ceramics with skeletons of LTP and TP crystals have been fabricated utilizing a novel finding that LTP is transformed into TP in acid solutions at temperatures 50°C. These integrated porous glass-ceramics are prepared from glasses in the pseudo-binary LiTi2(PO4)3Ca3(PO4)2system by controlled crystallization and subsequent acid treatment. Bulk samples with continuous pores of ∼ 30 and ∼ 50 nm diameters were obtained without serious cracking, or deformation. The synthesis route and procedures are reported with their microstructure and possible modifications.
