Microwave hybrid fast sintering of red clay ceramics

International Journal of Applied Ceramic Technology, 2021
Abstract This work aimed to examine the performance of the hybrid sintering of clay ceramic in a microwave furnace, compared to the sintering process in a conventional furnace. The raw materials were subjected to X‐ray fluorescence, loss on ignition (LOI), X‐ray diffraction, particle size distribution, real specific mass, and ...

Degradation of Red Ceramic with Incorporated of Petroleum Waste

Materials Science Forum, 2014
The red ceramic pieces Campos-RJ degrade easily when they are in the built environment. With the intention to reduce the degradation in these pieces, was introduced petroleum coke in red ceramic. Petroleum coke is a solid fossil fuel, black in color and about granular form.

Red Ceramic Wastes: A Calcined Clay Pozzolan

2015
The properties and hydration of blended cements containing from 8 to 40 % by mass of ceramic waste (CW) from different countries (Argentine and Czech Republic) are investigated. The mini slump, the heat released rate up to 48 h, the pozzolanic activity and the compressive strength at 2, 7 and 28 are determined. Hydration process is characterized by XRD

Red emission in Pr doped CaBi4Ti4O15 ferroelectric ceramics

Materials Science and Engineering: B, 2011
Abstract In this paper, Pr doped CaBi 4 Ti 4 O 15 ceramics were prepared by a traditional solid state method. Crystal structure and morphologies of the ceramics were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photoluminescence properties of the samples were investigated by a spectrofluorometer.

Properties and mechanism of red mud in preparation of ultra-lightweight sludge-red mud ceramics

Journal of Central South University, 2012
New ultra-lightweight sludge-red mud ceramics (ULSRMC) were prepared by red mud (RM), clay and dried sewage sludge (DSS). The properties and mechanism of RM in the preparation of ULSRMC were discussed. The chemical components, thermal properties and mineral phases of RM were determined by energy dispersive X-ray (EDX), differential scanning calorimetry/

Residual Coal Characterization for Addition to Red Clay Ceramics

Materials Science Forum, 2015
The high temperature firing to process clay ceramics requires some kind of fuel, which is associated with cost and embodied energy of the final product. Saving in fuel by introducing substances with heating power represents both economical and energetical advantages.

Nubian and southern Red Sea ceramics

2018
The article consists of the description of all the sherds imported from the southern Red Sea and of Nubian type from the Middle Kingdom harbor of Mersa/Wadi Gawasis. Some interpretative remarks are proposed as well on the meaning of the occurrence of these sherds, as well as on their contribution for understanding the location fo the land of Punt.
