Abstract:
1. A silica aerogel, free of a non-silica content, comprising: a network of primary silicate clusters comprising silica particles having diameters from 1 to 10 nm interconnected to form diversely-sized secondary silicate clusters having diameters greater than 20 nm, a porosity of greater than about 80 percent, a diverse range of pore sizes with pores of less than 5 nm in size and pores greater than 50 nm in size, wherein the range of pore sizes exhibits a distribution curve having full-width-half-max range of at least 30 nm, a bulk density between about 0.08 g/cm a surface area greater than about 800 m a flexural modulus less than about 1×10 a thermal conductivity less than about 14 mW/mK at one atmosphere of pressure.
