Carbon dioxide absorption devices combat global warming.

Advanced Ceramics Report, June, 2001

Toshiba Corp and Toshiba Ceramics Co Ltd say they have jointly developed a lithium silicate that surpasses other ceramics in the speed at which it absorbs carbon dioxide (CO2).

In a 20% CO2 gaseous environment at 500[degrees]C, 1 g of lithium silicate absorbs 62 mg of CO2 in one minute, while its predecessors achieve only 1.8 mg a minute.

Toshiba sees the development of lithium silicate as an important step toward the development of lighter, cheaper ceramics offering faster CO2 absorption rates, while its room temperature absorption capabilities offers the potential for practical devices for reducing CO2 emissions, such as consumer air cleaners.

In 1998, Toshiba announced that it had developed a lithium zirconia that absorbs 400 times its own...
