| titleOfInvention | Method for production of cellular fused silica |
| abstract | Cellular fused silica having a bimodal closed cell structure is produced by mixing finely divided silica with finely divided boron oxynitride as a cellulating agent, and heating the mixture to a temperature of at least the melting point of the silica, whereby the silica melts and is cellulated by gas generated as a result of decomposition of the boron oxynitride. The cellular silica consists of a multiplicity of primary closed cells defined by a matrix consisting essentially of silica, the matrix also containing a multiplicity of secondary macroscopic closed cells which are at least an order of magnitude smaller than the primary cells. Cellular fused silica bodies according to the method of the invention are characterized by superior mechanical strength in addition to extreme whiteness and high purity of color, as well as other desirable properties, and are particularly useful for high temperature thermal insulation. Carefully controlled and defined shapes having very smooth surfaces may be obtained. |
