“…Potassium (K 2 O) and sodium (Na 2 O) oxides generally originate from feldspars, hence the presence of P and Na in the EDX data. The low content of Fe is essential to produce white ceramics since it can lead to the development of a reddish colour during sintering [6,12].…”

“…The LS determines the degree of compaction and densification by analysing the linear variation with regard to the length of the sample after firing, which is essential for controlling the dimensions of the finished ceramic product [6]. The model yielded a positive value (0.06) for the regression coefficient of the FT (Eq.…”

Optimisation of the physical properties of rice husk ash (RHA) in ceramic materials was carried out using Response Surface Methodology. The independent variables, namely the firing temperature and residue content, were statistically combined in a Central Composite Design with the effects on water absorption, linear shrinkage, bulk density, apparent porosity and apparent specific gravity determined. Physical and microstructural analyses were carried out to obtain information on the processes that occurred within the ceramic materials. The results obtained were analysed to determine the optimum physical properties of the ceramic materials within the range investigated. The residue content had a significant influence (at 95% confidence level) on the bulk density, water absorption, apparent porosity and apparent specific gravity but not on the linear shrinkage. The firing temperature had a more significant effect on the linear shrinkage than on the residue content, so that when elevated it contributed to an increase in linear shrinkage. The optimum residue content and firing temperature to enhance physical properties within the range investigated were 5.85% RHA and 1029.64°celsius, respectively. These optimal conditions are expected to produce a ceramic material with a bulk density, linear shrinkage, apparent porosity, water absorption and apparent specific gravity of 1.64 g/cm3, 0.29%, 0.29 g/cm3, 18.26% and 2.11, respectively with a composite desirability of 100%.

“…The addition of quartzite had negligible effect on other properties such as plasticity and moreover, no costly modifications will be necessary for industrial production. In a more recent study, Ruiz Silva et al [155] investigated the use of quartzite residue in commercial porcelain tile. The authors carried out a deep physical-chemical and microstructural analysis in order to comprehend how quartzite waste content influenced the properties of green and fired bodies.…”

Mullite-Based Ceramics from Mining Waste: A Review

et al. 2021

Mullite (3Al2O3·2SiO2) is an aluminosilicate characterized by excellent physical properties, which makes it an important ceramic material. In this way, ceramics based on mullite find applications in different technological fields as refractory material (metallurgy, glass, ceramics, etc.), matrix in composite materials for high temperature applications, substrate in multilayer packaging, protective coatings, components of turbine engines, windows transparent to infrared radiation, etc. However, mullite is scarce in nature so it has to be manufactured through different synthesis methods, such as sintering, melting-crystallization or through a sol-gel route. Commonly, mullite is fabricated from pure technical grade raw materials, making the manufacturing process expensive. An alternative to lowering the cost is the use of mining waste as silica (SiO2) and alumina (Al2O3) feedstock, which are the necessary chemical compounds required to manufacture mullite ceramics. In addition to the economic benefits, the use of mining waste brings out environmental benefits as it prevents the over-exploitation of natural resources and reduces the volume of mining waste that needs to be managed. This article reviews the scientific studies carried out in order to use waste (steriles and tailings) generated in mining activities for the manufacture of clay-based ceramic materials containing mullite as a main crystalline phase.

This article shows the design of dielectric resonator antenna with nickel ferrite as dielectric material. Its main characteristics and measurements are described. Nickel ferrite was synthetized by sol–gel modified by ionic coordination reaction technique. Calcination was performed at 1100°C (10 h, 10°C/min step), followed by compression procedure at 227 MPa, to manufacture the bulk. Sintering process was applied at calcination temperature, for 4 h, to ensure bulk's physical resistance, and its electrical characterization was performed for antenna design and simulations. Simulated radiation patterns are presented, as reflection coefficient, which is compared with measurements. Measured reflection coefficient presented good agreement with performed simulations, with a difference of 0.74% in resonance frequency. Simulated radiation patterns also presented good results, with relatively high gain in co‐polarization planes, 2.11 dB for E plane, and low cross‐polarization E plane value, −47 dB.
