Abstract The study investigates mineralogical characteristics and thermal threshold at successive steps of Tikar pottery production chaine-operatoire from Bankim (Adamawa, Cameroon). It is a pilot study relying on X-ray diffraction (XRD), thermal ana... see more

Samples of 0.96(K0.48Na0.48Li0.04)(Nb0.95Sb0.05)O3-0.04Bi0.5(Na0.82K0.18)0.5ZrO3 piezoelectric ceramic were fabricated with conventional ceramic techniques and sintered at different temperatures. The effect of sintering temperature (TS) on the struct... see more

Traditional ceramic technology combined with a two-step sintering technique has been applied to prepare 0.96(K0.48Na0.48Li0.04)(Nb0.95Sb0.05)O3-0.04Bi0.5(Na0.82K0.18)0.5ZrO3 (KNLNS-BNKZ) piezoelectric ceramics. The experimental results show that the ceram... see more

 In this paper, influence of additives on structural properties of Tantalum (Ta) doped PZT ceramics, prepared by solid-state oxide and mechanical activation (MA) routes, has been studied. The Fourier transformation infrared spectroscopy (FTIR) studie... see more

Through an analysis on the relationship among ceramic properties, the depth of penetration (DOP) test parameters and the ballistic performance of armour ceramics based on literatures, the effects of ceramic type, tile thickness and projectile velocity on ... see more

The effect of aging on Sr2+ modified Lead Zirconate Titanate (PSZT) ceramics have been studied. Aging was assessed by the measurement of dielectric constant and dielectric loss tangent as a function of time and temperature. Dielectric constant and dielect... see more

The IEEE standard on piezoelectricity recommends methods to determine the coefficientsof piezoelectric ceramics and the sizes of the samples to be used. A method to determine thedifference between the actual coefficients and the coefficients determined us... see more

The influence of sintering temperature of 0.935(Bi0.5Na0.5) TiO3-0.065BaTiO3 lead-free ceramics was studied from 1150°C to 1200°C. The X-ray diffraction patternsshowed that all of the BNT6.5BT ceramics exhibited a single perovskite structure with the coex... see more

The cementation of thin ceramic veneers employing fluid light-activated resin-based materials is a common procedure in the dental practice. Aim: To evaluate the influence of ceramic thickness and shade on the degree of conversion (DC) of a flowable light-... see more
