Abstract
Official abstract text for this publication.
A product includes an aerogel having a single bulk structure, the single bulk structure having at least one dimension greater than 10 millimeters. The single bulk structure includes a plurality of pores, where each pore has a largest diameter defined as a greatest distance between pore walls of the respective pore. In addition, an average of the largest diameters of a majority of the pores is within a specified range, and the plurality of pores are distributed substantially homogenously throughout the single bulk structure.
First claim

What is claimed is: 1 . A product, comprising, an aerogel having a single bulk structure, the single bulk structure having at least one dimension greater than 10 millimeters, wherein the single bulk structure comprises a plurality of pores, wherein each pore has a largest diameter defined as a greatest distance between pore walls of the respective pore, wherein an average of the largest diameters of a majority of the pores is within a specified range, wherein the plurality of pores are distributed substantially homogenously throughout the single bulk structure. 2 . The product as recited in claim 1 , wherein an average of the largest diameters of a majority of the pores is in a range of about 500 nanometers to about 2000 nanometers. 3 . The product as recited in claim 1 , wherein an average of the largest diameters of a majority of the pores is in a range of greater than 50 nanometers to about 500 nanometers. 4 . The product as recited in claim 1 , wherein an average of the largest diameters of a majority of the pores is in a range of about 2 microns to about 10 microns. 5 . The product as recited in claim 1 , wherein an average of the largest diameters of a majority of the pores is in a range of about 10 microns to about 30 microns. 6 . The product as recited in claim 1 , wherein the single bulk structure has at least one dimension greater than 50 millimeters. 7 . The product as recited in claim 1 , wherein the aerogel is a carbonized aerogel. 8 . The product as recited in claim 7 , wherein the carbonized aerogel exhibits homogenous activation throughout the single bulk structure. 9 . The product as recited in claim 1 , wherein the aerogel has a uniform microstructure throughout the aerogel. 10 . The product as recited in claim 9 , wherein the uniform microstructure is defined as having a uniform pore structure. 11 . A plurality of products as recited in claim 1 formed in sequence, wherein the products have a defect rate less than 10%. 12 . The plurality of products as recited in claim 11 formed in sequence, wherein the products have a defect rate less than 5%.
