Abstract:
A new technique for avoiding cracks during drying is proposed; increasing the hydroxy groups in the gels. By this technique a drying rate of 1.33 g/h was attained, which is approximately 5 times faster than non-treated gels (0.27 g/h). Further, this technique can easily be applied to change the microstructure of the gels.
