✍ R Leboda; E Mendyk; A Gierak; V.A Tertykh 📂 Article 📅 1995 🏛 Elsevier Science 🌐 English ⚖ 500 KB

The effect of the duration of hydrothermal treatment (in the range 1-20 h) on the parameters of the pore structure of silica xerogels was investigated. Silica gels with different initial porous structure parameters were used. The specific surface area (S) of the adsorbents changed from 830 to 38 m 2

✍ R Leboda; E Mendyk; A Gierak; V.A Tertykh 📂 Article 📅 1995 🏛 Elsevier Science 🌐 English ⚖ 767 KB

The effect of hydrothermal treatment temperature (in the range 150-300°C) on the structural parameters of silica gels was investigated. Silica gels with different starting porous structures were used for modification. The specific surface areas of the modified sorbents varied from 830 to 12 m 2 g-1.
