Cathode ray tubes glass wastes used for vitrification of iron oxide rich waste resulted from the groundwater treatment

Vitrification and Sinter-Crystallization of Iron-Rich Industrial Wastes

Results about the vitrification of several hazardous iron-rich industrial wastes (from productions of Zn and Cu metals, as well as EAFD and MSWA) and the usage of obtained glasses for synthesise of sintered glass-ceramics are summarises. It is shown that the appropriated method of sinter-crystallization mainly depends on the crystallization trend of used glasses. When the parent composition is ...

Iron-Rich Sintered Glass-Ceramics from Industrial Wastes

In this study, sintered glass-ceramics made up of jarosite (a hazardous industrial waste) have been obtained by sintering high-iron-content glasses. Thermal gravimetry and differential thermal analysis, carried out in different atmospheres, have been utilized to explain the phase formations in the volume and iron oxidation on the surface of the glass particles. Low-angle XRD technique has been ...

Recycling of Cathode Ray Tubes (CRTs) in electronic waste

Production and Crystallization Behavior of an Iron Rich Glass–Ceramic Prepared by Ironmaking and Steelmaking Wastes

Using wastes as starting raw materials is a common method to reduce the production costs and the environmental pollution problems arising from such wastes. In this study the production and crystallization behavior of an iron rich glass prepared by iron and steel making wastes has been investigated. The raw materials used, were the blast furnace slag, the blast furnace dust, converter slag and s...

Thermogravimetric Investigation of the Lead Volatilization from Waste Cathode-Ray Tube Glass

The treatment of lead-containing cathode-ray tube (CRT) glass is an important environmental issue. One approach is the removal of lead by chloride volatilization. In the present work, the reaction of CRT glass with PVC as the chlorinating agent and Ca(OH)2 as the chlorine absorber was investigated by thermogravimetric analysis (TGA) in air. Seven reaction steps occurring at different temperatur...
