Waste-derived glass-ceramics fired in nitrogen: Stabilization and functionalization

Sintering in Nitrogen Atmosphere of Iron-Rich Glass-Ceramics

The sintering and the crystallization of two iron-rich glass compositions (45–75m powder fractions) were studied in air and nitrogen atmospheres. The phase formation was evaluated by differential thermal analysis, while the densification, by dilatometry; the crystalline phases were identified by X-ray diffraction and the structure observed by scanning electron microscopy. It was highlighted tha...

Magnetic Glass Ceramics by Sintering of Borosilicate Glass and Inorganic Waste

Ceramics and glass ceramics based on industrial waste have been widely recognized as competitive products for building applications; however, there is a great potential for such materials with novel functionalities. In this paper, we discuss the development of magnetic sintered glass ceramics based on two iron-rich slags, coming from non-ferrous metallurgy and recycled borosilicate glass. The s...

Innovative Technology Summary Reports are designed to provide potential users with the information they need to quickly determine if a technology would apply to a particular environmental management problem. They are also designed for readers who may recommend that a technology be considered by prospective users. Each report describes a technology, system, or process that has been developed and...

Moisture expansion and mass gain in fired clay ceramics

We report the first measurements of mass gain and expansive strain in clay ceramics immediately following firing. The results show that both mass gain and expansive strain follow a well defined two-stage process, each stage of which is linear with (time)1/4, with a transition from the first to the second stage commencing at t ∼ 1.5 h. The first stage mass gain and strain rates are ∼3.5 times gr...
