Latest Patents
One of Freeman's notable patents is titled "Polymer derived ceramic fibers having improved thermal stability." This invention relates to ceramic fibers of the Si-C-N-O series with a diameter of less than about 20 micrometers. It has been unexpectedly found that the thermal stability of these fibers can be increased by minimizing the impurity content, primarily the content of metals or metallic compounds. Such fibers with low levels of contaminants retain greater than about 60 percent of their initial tensile strength when subjected to temperatures of 1300°C-1400°C for at least 30 minutes in a non-oxidative environment. This advancement represents a significant step forward in the performance of ceramic materials.
