Thermoelectric properties of bottom-up assembled Bi 2 S 3– x Te x nanocomposites
Bi 2 S 3– x Te x bulk nanocomposites with crystal domain sizes in the range from 50 nm to 100 nm were obtained from the reaction of Bi 2 S 3 nanorods with Te powder. The thermoelectric properties of the obtained nanocomposites were analysed in the temperature range from 0ºC to 300ºC. We observed how the thermoelectric properties of the material improved with the ...

Thermodynamic analysis of efficient recovery and utilisation of waste heat resources during sintering process
Efficient recycling and utilisation of waste heat resources are among the primary methods in saving energy during sintering process, as waste heat resource recycling and utilisation are essentially energy conversion process. The purpose of this study is to analyse energy conversion and utilisation during the sintering process, and waste heat resources in each subsystem during the sintering ...

A novel method for extraction of alumina from red mud by divalent alkaline earth metal oxide and soda ash sinter process
A novel method for extraction of alumina from red mud by divalent alkaline earth metal oxide and soda ash sinter process followed by thermo chemical leaching in suitable caustic concentration at 105ºC for different times is presented in this paper. During sintering sodalite/cancrinite, gibbsite and boehmite in red mud is converted to sodium aluminate as well as stable phases of divalent alkaline ...

Introduction to Pyrolytic Boron Nitride (PBN)
Pyrolytic Boron Nitride, abbreviated as Pyrolytic BN or PBN, also known as Chemical vapour-deposited Boron Nitride, Chemical Vapour-deposition of Boron Nitride or CVD-BN, etc. As the name suggests, this is a kind of boron nitride prepared by high-temperature pyrolysis reaction by chemical vapor deposition method. Speaking of boron nitride, we must first talk about the two main structures of boron ...

High di-electric constant nano-structure ceramics synthesis using novel electric discharge assisted mechanical milling and magneto ball milling and its properties
The conventional method to prepare functional oxides is ceramic-powder-based processing typically via solid-state reaction of microcrystalline starting powders at high temperatures. Disadvantages of this approach include the high temperatures of reaction, limited degree of product chemical homogeneity and difficulties in achieving rapid sintering. Various chemical-based processing routes have ...

Magnetic Materials
Magnetic materials can produce magnetic fields, which generate forces attracting or repelling ferromagnetic materials and other magnets. Magnetic materials can be divided into soft and hard magnets. Soft magnets are those materials easy to magnetize and demagnetize, while hard magnets are difficult to do so and retain strong magnetism after the removal of applied magnetic field. Hard magnets are ...

Fly Ash & the Lightweight Aggregate Market
In 2015, the global fly ash market was estimated to be valued at 40 billion USD. A recent industry analysis by Research Nester anticipates the market will reach an estimated 70 billion USD by the end of 2023 – a 7.1% CAGR owing to increasing urbanization and a boost in construction projects. Along with bottom ash (BA) and flue gas desulfurization gypsum (FGD gypsum, or synthetic gypsum), ...
