Optimisation of sintered glass ceramics from an industrial waste glass.

Industrial plasma melting of municipal solid waste msw incinerator fly ashes leads to a glass that may be easily crystallised to gehlenite glass ceramics by the sintering of fine glass powders. The measured microhardness of this material was of 5 3 0 04 gpa which is a similar value of other waste derived glass ceramics. The sintered materials exhibit a well developed and reproducible glass ceramic microstructure comprising a silicate matrix with dispersed crystalline phases. Sintered glass ceramic samples of optimized composition glass clay waste weight proportion equal to 50 30 20 featured a water absorption below 2 a good specific strength and above all a substantially unchanged f content compared to the starting mixture.

Recent papers have shown that sinter crystallisation is a very effective process for obtaining strong and dense glass ceramics from waste glasses i e. The obtained glass ceramics can be potentially used for industrial buildings because of the sufficient mechanical strength. Request pdf optimisation of sintered glass ceramics from an industrial waste glass industrial plasma melting of municipal solid waste msw incinerator fly ashes leads to a glass that may be. Enrico bernardo giovanni scarinci erika edme ulysse michon nicholas planty fast sintered gehlenite glass ceramics from plasma vitrified municipal solid waste incinerator fly ashes journal of the american ceramic society 10 1111 j 1551 2916 2008 02892 x 92 2 528 530 2009.

The production of glass ceramic materials based on inorganic industrial waste generated by different industries is a promising line and has been used very successfully to crystallize important ceramics from the glass phase. The aim of this study was to optimize the main parameters of the process for production of glass ceramics from fly ash and waste glass by using response surface method 19. Two step thermal process. The matrix was b 2 o 3 fe 2 o 3 cao sio 2 al 2 o 3 glass with one of the crystalline phases enriched in metals especially iron and titanium.

Synthesis of an original glass composition with specific sinter. Glasses from the melting of several kinds of industrial waste the technology relies on the viscous flow sintering of fine glass powders with concurrent crystallisation in turn due to a surface mechanism.
