Glass–Ceramic Foams from Borosilicate Glass Waste

International Journal of Applied Glass Science, 2014
In this study, we reported the studies on a glass–ceramic foam with wollastonite and cristobalite micrometric crystals prepared by sintering a borosilicate glass waste with organic binder as foaming agent. The waste glass, coming from the dismantling of washing machine, was characterized by high CaO content and low‐temperature ...

Glass foam of macroporosity using glass waste and sodium hydroxide as the foaming agent

Ceramics International, 2013
Abstract Glass foams using float glass waste and sodium hydroxide were produced. The influence of the sodium hydroxide amount in the foam formulation was studied. Titanium dioxide was used as a strengthening agent. The variations of temperature, heating rate and sintering time were investigated during the synthesis process.

Influence of the glass particle size on the foaming process and physical characteristics of foam glasses

Journal of Non-Crystalline Solids, 2016
We have prepared low-density foam glasses from cathode-ray-tube panel glass using carbon and MnO2 as the foaming agents. The effect of the glass particle size on the foaming process, the apparent density and the pore morphology is revealed. The results show that the foaming is mainly caused by the reduction of manganese. Foam glasses with a density of &

Glass Foams

2006
Foam glass possesses an unique combination of properties, since it is lightweight, rigid, compression resistant, thermally insulating, frost resistant, non-flammable and flame resistant, chemically inert and non toxic, rodent and insect resistant, bacteria resistant, water and vapour resistant.

Effect of Foaming Temperature and Holding Time on Foam Glass

Advanced Materials Research, 2013
In the paper, the effects of the foaming temperature and holding time on the quality of the foam glass were investigated by means of the different foaming technology. The results indicated that lots of the defects, such as the non-uniform size of the bubbles, big hole and the pit at the bottom, were caused by the high foaming temperature. The fine pore

The mechanism of foaming and thermal conductivity of glasses foamed with MnO2

Journal of Non-Crystalline Solids, 2015
We prepare foam glass from cathode ray tube (CRT) panels using MnO2 as foaming agent at different temperatures for various durations. The reduction of MnO2 to Mn2O3 leads to formation of O2 gas, and hence, causes initial foaming. The Mn2O3 particles dissolve into the glass melt and subsequently reduce, causing further formation of O2 gas and foaming of

Radiation Characteristics of Glass Foams

Journal of the American Ceramic Society, 2000
This paper is concerned with the analysis of the radiative heat transfer in glass foams. The closed‐form analytical model for the reflectance, transmittance, and absorptance of radiation by a foam layer has been utilized to assess the resistance of radiation heat transfer from the hot combustion gases and refractories to the molten glass in the ...

Mechanism of foam-glass formation

Glass and Ceramics, 2008
The mechanism of thermal dissociation of a carbon foaming agent is determined and the parameters of the foam-glass formation process are calculated. Promising directions for improving the foaming process are determined.

Recycle Glass in Foam Glass Production

2014
The foam glass industry turn recycle glass into heat insulating building materials. The foaming process is relative insensitive to impurities in the recycle glass. It is therefore considered to play an important role in future glass recycling. We show and discuss trends of use of recycled glasses in foam glass industry and the supply sources and ...

From the bubble to glass foam

2023
Les verres d’usage courant sont produits dans des fours de grande taille. Les matières premières portées à haute température y réagissent pour former un liquide très visqueux libérant une grande quantité de CO2. Pour réduire l’empreinte carbone et préserver les ressources minières, l’utilisation de verre recyclé est devenue inéluctable.Nous montrons ...
