Abstract
The microstructure and phase composition of a lithium titanium phosphate glass-ceramic was studied. The porous material with open porosity was obtained as a result of thermal treatment. The main crystalline phase detected was lithium titanium phosphate (LiTi2(PO4)3). Particles of the crystalline phase are very uniform in shape, with mean diameter of 2 mu m and the size of pores ~0.5 μm. It has been shown that such a glass-ceramic material can be utilised as a humidity sensor. The sensor under study works reversibly and is linear in the humidity range 6-95% RH.
