| Abstract: | Alkali-resistant mechanism of Na_2O-SiO_2-ZrO_2-TiO_2 system glasses has been investigated pre-liminarily by means of spectrophotometry, atomic absorption spectrophotometry and electron probemicroanalysis (EPMA). It is found that the thin layer of ZrO_2-TiO_2-rich has formed on the surfaceof the glasses with different ZrO_2/TiO_2 ratio after alkali corrosion. Only the thin layer formed by theglasses with high ZrO_2 and low TiO_2 can block alkali attack effectively. In the paper, the alkali extraction behaviours and remaining behaviours of ZrO_2, TiO_2, SiO_2 andetc. On the surface of glassfibers are discussed with correlation analysis in statistics. It is found thatthe remaining behaviour of ZrO_2 and TiO_2 in layer are different. It show that the mechanism of ZrO_2and TiO_2 react with alkali are different. |
