How To Make Ferrofluid. Ferrofluids are made up of tiny magnetic fragments of iron suspended in oil (often kerosene) with a surfactant to prevent clumping (usually oleic acid). The fluid is relatively easy to make at home yet extremely expensive to buy on-line. How does $165 a liter sound? Pretty bad, right? How to Make Liquid Magnets - Synthesize Ferrofluid.
A liquid magnet or ferrofluid is a colloidal mixture of magnetic particles (~10 nm in diameter) in a liquid carrier.
The carrier contains a surfactant to prevent the particles from sticking together. Ferrofluids can be suspended in water or in an organic fluid. A typical ferrofluid is about 5% magnetic solids, 10% surfactant, and 85% carrier, by volume. One type of ferrofluid you can make uses magnetite for the magnetic particles, oleic acid as the surfactant, and kerosene as the carrier fluid to suspend the particles. Several people have asked me if they can make substitutions for the oleic acid and the kerosene. Liquid Chrome Aerosol - The World's Most Reflective Chrome Paint! 6 lb.

Packaging Liquid Metal Thermal Interface Materials - Amanda Hartnett. Liquid metal. Consists of gallium-contained alloys with very low melting points.
(Tetraamminelithium (Li(NH 3 ) 4 ) is a conductive gold bronze colored liquid, has a melting point of 89K, 150K below that of Mercury, and is classified as an expanded metal.) These low melting point alloys are liquid at room temperature. [ 1 ] The standard used to be mercury but gallium -based alloys are being used as a replacement in various applications. Mercury has a high vapor pressure at room temperature. [ 2 ] These alloys have reduced toxicity and a lower vapor pressure than mercury.
Alloy systems that are liquid at room temperature have a high degree of thermal conductivity far superior to ordinary non-metallic liquids. [ 3 ] This results in the use of these materials for specific heat conducting and/or dissipation applications. Other advantages of liquid alloy systems are their inherent high densities and electrical conductivities. Metal recipie. A non-toxic liquid metal alloy mercury substitute.
Suppose you had a metal alloy that had the advantages of liquid mercury, but without the toxic effects? You could make your own barometers and thermometers, and not worry about calling in a hazardous materials team to clean up after any accidents. You could simply wipe up the mess with a paper towel. You wouldn't have to worry about breathing in toxic mercury fumes, but you could still make neat little electric motors that dip into liquid metal to make their electrical connections.
