Sk. Evstropev et al., NEW HIGH-EFFICIENCY SILICA-GEL FOR PROTECTING OPTICAL-DEVICES FROM ATMOSPHERIC MOISTURE, Journal of optical technology, 65(2), 1998, pp. 158-160
Silica gel with high capacity (about 1 g of water per 1 g of sorbent),
a narrow distribution of pore size (about 100 Angstrom), and a corres
ponding reversibility in the interval of relative water-vapor pressure
s of 0.8-0.9 has been produced and studied. The high mechanical streng
th of the porous material ensures that there is no dust in the volume
to be dried and makes it possible to form items with various configura
tions and sizes. (C) 1998 The Optical Society of America.
