“…The two materials show a similar performance but the syntactic foams are marginally less attractive for lightweight panels owing to their high density. [1][2][3][4][5][12][13][14][15] The energy absorbed is higher per unit volume or mass than for the equivalent porous metal, but much lower than for "conventional" syntactic foams. The much-reduced load drop in the foams presented in this study means that they show high energy absorption efficiencies (85-90%) that are more typical of metal foams and porous metals than "conventional" syntactic foams.…”

Expanded glass particles (EGP) have been used to manufacture Al syntactic foams using a simple vacuum casting method. Clamping of the casting in the stainless steel mould was observed when preheating the mould to >400°C, causing damage to the EGP, resulting in a weaker foam but with the significant advantage of eliminating the yield drop, improving the energy absorption characteristics. The same effect in castings that were not clamped (for mould preheats < 400°C) could be achieved by quenching in liquid nitrogen. These "low strength" syntactic metal foams are a costeffective alternative to metal foams and porous metals (in terms of specific strength, stiffness and energy absorption) rather than "conventional" syntactic foams which contain smaller, stronger, hollow microspheres.

“…The treatment level of industrial solid waste in thermal power plants (TPP) is, currently, extremely low that leads to a considerable accumulation of bottom ash waste in ash-disposal areas [1][2][3]. The core aspect of ash waste utilization is a high melting temperature (up to 1700°С) which depends on heterogeneity of its chemical composition.…”

Abstract. The paper deals with the plasma-chemical synthesis of melts produced from the bottom ash waste for the production of new construction materials with enhanced performance characteristics. Phase composition of the plasma-treated bottom ash waste is detected by the Xray diffraction analysis. The bottom ash waste is a mixture of SiO 2 minerals. The structure and phase composition of this mixture are investigated after the plasma treatment. The obtained results are compared with the original state of the mixture. The identification and the qualitative content of ash waste as a multi-phase system are complicated by the overlapped reflections and a possible existence of the intermediate amorphous phase.

“…Most researches have been focused on the variation of their compressive strength and energy-absorbing capacity in terms of the microballoon volume fraction 1,2) and its relative wall thickness. [3][4][5] The improvement of other mechanical properties such as the stiffness 6) and fracture toughness 7) of the syntactic foams has been also observed. Strength, modulus, fracture toughness, and energy-absorbing capacity of the syntactic foam have been further improved by incorporating the third materials in the form of particle or short fiber into it.…”

Prediction of Thermal Conductivity of Composites with Spherical Microballoons

A new model for predicting the thermal conductivities of a composite with spherical microballoons is proposed and consists of two consecutive procedures, the computation of the thermal conductivity of the microballoon and the composite. The microballoon is first replaced by the equivalent filler of a known thermal conductivity, so the composite is treated as the matrix containing the equivalent fillers and its thermal conductivity is derived by using Eshelby model modified with Mori-Tanaka's mean field approach. The present model is validated comparing the predicted, experimental, and numerical results from the literature. Parametric studies in terms of the microballoon volume fraction, its relative wall thickness, and the thermal conductivity ratio of the shell to the matrix have been made and their results are discussed.
