1-52. (canceled)
A preceramic resin for forming a polymer-derived ceramic material, said resin comprising a first functionalised organosilicon monomer having a first ceramic yield of no greater than 50%, and one or more of:
- a) a second functionalised organosilicon monomer having a second ceramic yield, wherein the second ceramic yield is greater than the first ceramic yield by at least 5%;
- and
- b) ceramic particles.
