This review provides a comprehensive analysis of the effects of zinc doping on three prominent ferrite materials: MnFe2O4, CuFe2O4, and CaFe2O4. Zinc doping, as a strategic method for tailoring these properties, has emerged as a promising avenue for enhancing their functionality and versatility. In the introduction part to the significance of ferrites, their wide-ranging applications are discussed. This review provides a basic overview of the many synthesis methods, such as co-precipitation, sol–gel, hydrothermal, solid-state etc., and a detailed investigating some nano ferrites. It then delves into the distinct characteristics of each ferrite, highlighting their magnetic behaviors, structural features, and electrical properties. The different methods to study the structural, magnetic, and dielectric properties are also discussed. The effects of zinc doping on MnFe2O4, CuFe2O4, and CaFe2O4 ferrites are discussed comprehensively. This study extensively concentrates on recent industrial applications like photoluminescence, biomedical, and sensors using spinel ferrites.","PeriodicalId":595,"journal":{"name":"International Journal of Self-Propagating High-Temperature Synthesis","volume":"33 3","pages":"165 - 182"},"PeriodicalIF":0.5,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142214067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Generally, alumina is manufactured with a purity of 99.6–99.9% mainly by the Bayer process with bauxite as the starting material. It is used in refractory products, spark plugs, IC substrates, and so on. High-purity alumina (HPA), which has a purity of more than 99.99% and has a uniform fine particle, is widely used in translucent tubes for high-pressure sodium lamps, single crystal materials such as sapphires for watch covers, high-strength ceramic tools, abrasives for magnetic tape, and the like. In recent years, the demand for high-purity alumina has been expanding in fields that are expected to show a high growth rate e.g., display materials, energy, automobiles, semiconductors, and computers. There are several complicated processes reported in literature to produce single phase α-HPA, which consumes more energy, and power and are very costly. In this paper, we report the preparation of nano-α alumina powders with a purity of 3N (99.9%) by a simple, economical, and faster method i.e., one-step auto combustion method. To obtain single phase α-alumina, the calcination temperature required is 1200°C but, in our work, we achieved single phase α-alumina at 500°C temperature by one-step auto combustion method. The as-prepared HPA is characterized through XRD, BET surface area, SEM and ICP, TGA, and LIBS to test for purity and its application in LED fabrication.","PeriodicalId":595,"journal":{"name":"International Journal of Self-Propagating High-Temperature Synthesis","volume":"33 3","pages":"223 - 227"},"PeriodicalIF":0.5,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142214071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Leucoxene and C were combined at a molar ratio of 1.0 : 1.5, and the effect of magnesium (Mg) fuel in the reaction system was studied at ratios of 1.0, 1.5, 2.0, 2.5, and 3.0. XRD analysis showed that the as-leached powder from a reactant mixture with a Mg molar ratio of 3.0 has fewer unwanted phases, and that leucoxene, C, Mg mixed at 1.0 : 1.5 : 3.0 produce TiC powder of a higher purity than the other reacted mixtures. The higher purity of the product was due to the more exothermic character of the combustion reaction, which had a higher enthalpy of reaction (ΔH) and adiabatic temperature (Tad). SEM observation of the as-leached powder revealed agglomerated fine particles of sub-micrometer size. The TiC powder was successfully coated with nickel by an electroless plating process. SEM/EDX demonstrated that the Ni-coated TiC powder consists of Ni particles smaller than 500 nm, which are well distributed on TiC particles.","PeriodicalId":595,"journal":{"name":"International Journal of Self-Propagating High-Temperature Synthesis","volume":"33 3","pages":"228 - 236"},"PeriodicalIF":0.5,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142214072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
