Durable phosphate ceramic structures and their preparation |
摘要 |
Processes are described for producing strong, durable fiberous phosphate ceramic structures. Stronger fiberous phosphate ceramic structures can be produced by applying higher pressures during the reaction of phosphoric acid, a metal oxide selected from the group consisting of zinc oxide, calcium oxide, magnesium oxide, and aluminum oxide; and calcium silicate within a matrix of the fiber, or the fiber and a binder.
