Selective Glass Batching

Selective batching is a patented method (US Patent 7,260,960) of manipulating glass raw materials such that the melting time is reduced by up to 80% compared to traditional methods. The end result is reduced energy, pollution, and increased plant productivity.

"On the left (image 1) is an E-glass composition using traditional mixing techniques after 45 minutes at 1350 degrees Celsius. On the right (image 2) is the same composition at the same time and temperature, but prepared using the selective batching technique. Note the significant reduction in the amount of unmelted material."

Nanocoating

CSL Materials has developed a patent-pending method of coating ceramic particles with sub-micron particles. The technology is used to evenly distribute sintering dopants, leading to ceramics with improved strength and electrical properties.

"To the left (image 1) is a SEM image of uncoated, commercial alumina powder. To the right (image 2) is an image of the same alumina powder at the same magnification, but it has been coated with nano-sized silica using CSL's proprietary method. The silica is evenly distributed over the alumina surface."

"This image shows the closed porosity of a manufactured ceramic aggregate. The closed pores give it a low density but do not allow absorption of water."

Lightweight Ceramic Aggregate from Waste Materials

CSL Materials uses its extensive knowledge of ceramic processing and raw materials to make a strong, lightweight ceramic aggregate from a variety of waste and low value feedstocks. When used in concrete, a 30%+ increase in compressive strength can be achieved. The result is a high strength, low density concrete that reduces the overall amount of concrete required and allows novel designs for bridges and buildings.
