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.

Optimisation of sintered glass ceramics from an industrial waste glass.

The sintered materials exhibit a well developed and reproducible glass ceramic microstructure comprising a silicate matrix with dispersed crystalline phases. The measured microhardness of this material was of 5 3 0 04 gpa which is a similar value of other waste derived glass ceramics. 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. Two step thermal process.

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. The obtained glass ceramics can be potentially used for industrial buildings because of the sufficient mechanical strength. Synthesis of an original glass composition with specific sinter. 28 figure 5a shows the typical.

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. 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 technology of granite like glass ceramics from hazardous industrial wastes is based on the following steps. 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 hazardous industrial waste used may range from 50 to 70 percent of the raw material used which is higher in comparison to other similar technologies. 20 28 in addition the coefficient of thermal expansion 9 5 10 6 c 1 is also comparable to the ones already measured in waste derived glass ceramic materials.
