The Co-Zn ferrite (x=0.00) and Nickel doped Co-Zn ferrites (x=0.24) was synthesized by low cost solid state reaction method and characterized by XRD technique. The X-ray diffraction results for the samples showed the formation of single phase cubic spinel. The lattice constant and particle size for Co-Zn ferrite(x=0.00) is found to be 8.3465 Å and 26.72 nm and for Nickel doped (x=0.24) it is 8.3440 Å and 24.21nm. Micro strain (ε), Dislocation density(ρD), Hopping lengths (LA and LB), Bond lengths (A - O and B-O), Ionic radii (rA and rB), Texture coefficients (Thkl) and Standard deviation (σ) are also reported. The particle size is confirmed by scanning electron microscope (SEM). The Williamson-Hall plot and stress-strain plot also employed to understand the mechanical properties of materials.

“…As a result, strain broadening and size are both additive components of the total. In a study by Williamson and Hall [15], a distinct angle (q) dependent on each effect laid the groundwork for the separation between dimensions and strain broadening. The SSP is a tool for interpreting the quantity of isotropic nature and microstrain contribution, with the benefit of giving less weight to data from high-angle reflections, as illustrated in Fig.…”

This research aims to analyze nanoparticles made by adjusting the pH value in the coprecipitation synthesis process with the help of aluminum chloride. The prepared samples are pH adjusted using ammonium hydroxide. The samples are calcined at 650 °C and the pH values of the synthesized samples are 8, 9, 9.5 (S1, S2, S3). X-ray diffraction (XRD) analysis of the prepared samples confirms their orthorhombic structure. The average crystal size of the prepared -Al2O3 samples is 3.650, 2.741 and 2.806 nm for S1, S2and S3, respectively. The lattice parameter is in the range of 5.59 to 5.63 for a, 5.57 to 5.69 for b, and 23.75 to 23.79 for c, pH  8, 9, and 9.5, respectively, according to XRD analysis. The volume is 740 to 759 Å 3 , dislocation density (D) is in the range from 2.020 to 3.353 and mechanical characteristics (strain) are among the parameters provided. The Williamson-Hall and size-strain plots are both examined extensively. The results are compared showing that the crystal size of the sample is in the range of 2.2 to 2.8 nm and the strain is between 0.0193 to 0.0702 as per the W-H plots, and for the SS plots, the crystal size is in the range of 0.97 to 1.35 nm and the strain is between 0.314 to 0.409.

“…For the production of ferrite gas sensors, several techniques have been studied. As examples of these, solid state method [42], decomposition [43], chemical precipitation [44,45], sol-gel [46], self-combustion [47], citrate [33,34], co-precipitation [24,25,48,49]. The preparation of multi component oxides is considerably easier and more effective when done using coprecipitation [49].…”

Gas sensors that are highly sensitive, stable, and selective are increasingly in demand to detect toxic gases. As a result of the need to monitor concentrations of these gases, humans, animals, and the environment are all protected. Metal ferrites (AFe2O3, where A is a metal) are a major factor in this field. The development of ferrite gas sensors has made remarkable advances in the detection of toxic gases from vehicle exhaust, biological hazards, environmental monitoring, and pollution monitoring over the last decade. It is important for ferrite gas sensors to consider parameters like phase formation, crystallite size, particle size, grain size, dopants, surface area, sensitivity, selectivity, operating temperature, gas concentration, response time, and recovery time. There are various materials for gas sensing use such as carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), ethyl alcohol (C2H5OH), hydrogen sulfide (H2S), C2H5COOH, oxygen (O2), hydrogen (H2), chlorine (Cl2), NH3, C4H10, CH3COOH, gasoline, acetylene, petrol, and liquefied petroleum gas (LPG). Various methods are used to prepare ferrite gas sensors. Additionally, a brief description is provided of the various methods employed for synthesizing ferrite gas sensors. A comprehensive survey of ferrites as gas sensors, such as nickel, copper, zinc, cadmium, cobalt, magnesium, manganese, and multi-component ferrites, prepared by various methods.
