N2 - Drying behavior for lithium aluminosilicate gels was observed during low temperature natural evaporation. The mole ratio of water to tetraethyl orthosilicate (TEOS) was either 2:1, 4:1 or 8:1. The solvent was methanol. Both lithium and aluminum were added as nitrates. It was found that total drying shrinkage was independent of drying rate. Shrinkage was anisotropic with respect to radial and axial dimensions. However, by monitoring weight loss and volume reduction, a drying schedule was designed to produce crack-free cylinders.
