Ceramic Aerogel Composite

Atomic layer deposition grows thin film layers of materials using sequential exposure of a substrate to gas molecules. Researchers at Purdue University are using a graphene aerogel substrate and depositing thin layers of aluminum oxide ceramic to create a new material that is light, elastic, strong, conductive, and offers thermal insulation. This has excellent potential […]

Ceramic Metal Composites

CERMETs are composites of ceramics combined with metals. Most ceramics are oxides of aluminum, magnesium, and beryllium. They are typically strong but brittle and offer both thermal and electrical insulating attributes. Metals on the other hand are more malleable and are usually good thermal and electrical conductors. Combinations of these features offer innovative applications. Rapid […]

-3500 – glass

Naturally occurring volcanic glass (obsidian) was use before we learned to make glass around -3,500 in Egypt and Mesopotamia. The earliest form of glass made by humans was probably glazes that were used on ceramic pots. By mixing crushed quartz with calcite (calcium carbonate) from limestone, a solution is produced which can be fired into […]

New Composites Formed Using Magnetic Particles

Composites are made by combining two different materials with different properties: Concrete – concrete by itself is a composite of cement and crushed rock, which has a high strength against compression or crushing (like rock) but can be poured like a liquid into forms to create specific shapes before it hardens. Concrete does not have […]
