A Quantitative Texture Analysis approach to polycrystal piezoelectric and ferroelectric phenomena isgiven. Monocrystal longitudinal piezoelectric moduli are expanded in Bunge's symmetry- adaptedfunctional bases. Suitable expansion coefficients are given. Orientation Distribution Function basedalgorithms for polycrystal piezo-moduli prediction are presented. Significant odd-order expansion termsare calculated and their relation to ghost phenomena is commented. Polycrystal ferroelectricity ischaracterized. Quantitative describers associated to crystallographic and electric orientation distributionsare presented and related. Their evolution during heat and poling processes is discussed. Two computer-simulatedexamples are analyzed: (a) Texture-modulated longitudinal piezo-modulus is calculated foran ideal quartz single-component texture. (b) Barium titanate fibre texture transformation during ahypothetical technological process is investigated.
