Lithium silicate gels with 15 mol% Li2O were prepared by combining a lithium nitrate solution with partially hydrolyzed tetraethyl orthosilicate (TEOS). Using low pH and high water levels, samples were cast, gelled, and dried to form cylinders 30 mm in length and 5 mm in diameter in about a week. The dried gels had a uniform lithium content throughout. Lithium disilicate crystals and quartz crystals appeared in samples heated above 600°C.
