Engineered for Applications on This World and Beyond

The Sigma-Aldrich® commitment to carbon materials research and product development spans more than two decades. Understanding how thermodynamic and kinetic properties affect performance characteristics of both existing and novel carbons is our primary focus. The knowledge gained from this fundamental research has led to innovative new carbons and subsequent advances in the performance of many others. Today, we offer over 45 different carbons ranging in particle size from <0.2 to 841 μm and surface areas from 5 to 1,500 m2/g.

The unique and valuable characteristics of our carbon materials warranted their inclusion in experiments onboard the 1995 Galileo Mission to Jupiter, the 2005 Cassini-Huygens Missions to Saturn’s largest moon Titan, and the 2007 Phoenix Mission to Mars.

An important area of rapidly growing interest is the use of mesoporous and high surface area carbons in supercapacitor research. A list of selected Sigma-Aldrich carbon materials and their physical characteristics are shown in the Table 1.
