Joint preparation of CsH_5(PO_4)_2 whisker and mesoporous phosphosilicate glass

In this study,the CsH5(PO4)2 whiskers and mesoporous phosphosilicate matrix were derived simultaneously from the sol-gel synthesis of tetraethoxysilane(TEOS),orthophosphoric acid(H3PO4) and CsH2PO4 as raw materials,followed by hydrothermal treatment,and aging at room temperature.The obtained CsH5(PO4)2 whiskers have diameters between 1.5-10μm,while mesoporous phosphosilicate matrix possesses a average pore size of 27nm.The unique process,in which mesoporous structure matrix was prepared simultaneously accompanied with the growth of whiskers,could become a kind of method preparing mesoporous materals.
