Small, light weight and multifunctional electronic components are attracting much attention
because of the rapid growth of the wireless communication systems and microwave …

The binary niobate ceramics, with the formula M2+ Nb2O6 where M2+= Ca, Mg, or a
transition metal (TM), have the orthorhombic columbite structure. The best‐known members …

The preparations of (K0. 5Na0. 5) NbO3 (KNN)‐based ceramics were studied as lead‐free
piezoelectric materials. The authors found that the addition of CuO greatly enhanced the …

Lead-free ceramics KxNa1− xNbO3 doped with MnO2 and CuO have been fabricated by an
ordinary ceramic technique. The ceramics have an orthorhombic perovskite structure. Our …

The BiVO4 additive was found effective for low‐temperature firing of ZnNb2O6
polycrystalline ceramics below 950° C in air without a serious degradation in their …

Abstract CuO-doped K 0.5 Na 0.5 NbO 3 (K 0.5 Na 0.5 NbO 3+ x mol% CuO) lead-free
ceramics have been prepared by an ordinary sintering technique. The results of x-ray …

Copper is well known for its multifunctional biological effects including antibacterial and
angiogenic activities, while silicon-containing bioceramic has proved to possess superior …

The effects of Ni substitution for Zn on microwave dielectric properties of (Zn 1− x Ni x) 3 Nb
2 O 8 (x= 0.02–0.08) ceramics were investigated in this study. The XRD patterns of the …

The addition of B2O3 to Ba5Nb4O15–BaNb2O6 significantly lowered the sintering
temperature to∼ 900° C in comparison to∼ 1250° C for samples without B2O3. The …

In this study, the traditional mixed oxide process was used to create ZnNb2O6-chopped
strands composites. The single phase compound with the chemical formula ZnNb2O6 was …
