Aluminium carbonate (Al 2 (CO 3) 3), is a carbonate of aluminium.It is not well characterized; one authority says that simple carbonates of aluminium are not known. [2] However related compounds are known, such as the basic sodium aluminium carbonate mineral dawsonite (NaAlCO 3 (OH) 2) and hydrated basic aluminium carbonate minerals scarbroite (Al 5 (CO 3)(OH) 13 •5(H 2 O)) and ...
Open-cell metal foam CFD (numerical) simulation of fluid flow and heat transfer on an open cell metal foam. Open-celled metal foam, also called metal sponge, [3] can be used in heat exchangers (compact electronics cooling, cryogen tanks, PCM heat exchangers), energy absorption, flow diffusion, CO 2 scrubbers, flame arrestors, and lightweight optics.

Stabilized Aluminum Foam cast by Cymat Technologies. Consist of Alumina, Titanium diboride, Zirconia, Silicon Carbide, Silicon nitride or any solid stabilizer materials; Must compose of less than 25 vol% of the MMC; Particulate sizes must range from 0.5 μm – 25 μm, preferably in the range of 1 μm to 20 μm
Aluminium foam sandwich (AFS) is a sandwich panel product which is made of two metallic dense face sheets and a metal foam core made of an aluminium alloy. AFS is an engineering structural material owing to its stiffness-to-mass ratio and energy absorption capacity ideal for application such as the shell of a high-speed train .
The original foam was a mixture of two powders and water produced in a foam generator. It was called chemical foam because of the chemical action to create it. In general, the powders used were sodium bicarbonate and aluminium sulfate , with small amounts of saponin or liquorice added to stabilise the bubbles.
Syntactic foam, shown by scanning electron microscopy, consisting of glass microspheres within a matrix of epoxy resin.. Syntactic foams are composite materials synthesized by filling a metal, polymer, [1] cementitious or ceramic matrix with hollow spheres called microballoons [2] or cenospheres or non-hollow spheres (e.g. perlite) as aggregates.
When coated with a 50–100 nanometer layer of aluminum oxide, the material was able to withstand loads of as much as 280 megapascals, stronger than any other known material whose density was less than 1,000 kilograms per cubic metre (1,700 lb/cu yd), that of water.
A foaming agent is a material such as a surfactant or a blowing agent that facilitates the formation of foam.A surfactant, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles.
