Abstract
Crystals of compounds of the type (K, Rb, Tl, NH.sub.4)TiO(P, As)O.sub.4 with the proviso that when NH.sub.4 is present, As is absent, can be grown by hydrothermal methods. The crystals are optically biaxially positive, and piezoelectric and are useful in parametric amplifiers, oscillators, second harmonic generators, modulators and the like.
