A Practical Method for Production of Foamed Glass


A two stage preparation method of foamed glass is described here aimingto achieve reproducibility and convenience. Fritting of the solid components assembles the first stage; where firing a mix of the frit, foaming agents and the liquid component gather the second stage. Almost uniform cellular structure of the foamed glass is achieved at elatively low firing temperature of the mix (820°C for 10 min). The cellular structure is enclosed with a shell of continuous surface. Physical properties (density, porosity and water absorption) are measuredfor the product along with the mechanical properties that concerns production of building blocks, namely impact and compression strength.The flexibility of the presented two stage preparation method simplifiesfuture attempts to modify its properties to adapt particular applications.
