    Abstract: Disclosed is a method of fabricating a preceramic polymer for making a ceramic material including a metal boride. The method includes providing a starting preceramic polymer that includes a silicon-containing backbone chain and first and second reactive side groups extending off of the silicon-containing backbone chain, reacting a boron-containing material with the first reactive side group to bond a boron moiety to the silicon-containing backbone chain, and reacting a metal-containing material with the second reactive side group to bond a metal moiety to the silicon-containing backbone chain such that the preceramic polymer includes the boron moiety and the metal moiety extending as side groups off of the silicon-containing backbone chain. Also disclosed is a preceramic polymer composition and a metal-boride-containing ceramic article fabricated from the preceramic polymer.

    Abstract: Disclosed is a method for fabricating a ceramic material from a preceramic polymer material. The method includes providing a preceramic polymer material that has a preceramic polymer and an electromagnetic radiation-responsive component. The electromagnetic radiation-responsive component is selected from boron-containing compounds, cobalt, titanium, zirconium, hafnium, tantalum, tungsten, rhenium, nitrides of aluminum, nitrides of titanium, nitrides of zirconium, nitrides of hafnium, nitrides of tantalum, nitrides of tungsten, nitrides of rhenium, carbides of aluminum, carbides of titanium, carbides of zirconium, carbides of hafnium, carbides of tantalum, carbides of tungsten, carbides of rhenium and combinations thereof. An electromagnetic radiation is applied to the preceramic polymer material. The electromagnetic radiation interacts with the electromagnetic radiation-responsive component to generate heat that converts the preceramic polymer to a ceramic material

    Abstract: Disclosed is a method for providing a crystalline ceramic material. In an example, the method includes providing a silicon-containing preceramic polymer material that can be thermally converted to one or more crystalline polymorphs. The silicon-containing preceramic polymer material includes dispersed therein an effective amount of dopant particles. The silicon-containing preceramic polymer material is then thermally converted to the silicon-containing ceramic material. The effective amount of dopant particles enhance the formation of at least one of the one or more crystalline polymorphs, relative to the silicon-containing preceramic polymer without the dopant particles, with respect to at least one of formation of a selected polymorph of the one or more crystalline polymorphs formed, an amount formed of a selected polymorph of the one or more crystalline polymorphs formed, and a temperature of formation of the one or more crystalline polymorphs.
