Latest Patents
Yuan-Fu Yu's latest patents include a formulation for preceramic polysilazane compositions. This crosslinkable composition is designed for use as an infiltrant or binder for ceramic powders, such as silicon carbide and silicon nitride. The formulation comprises about 40-70% by weight of a low molecular weight polysilazane, 15-35% by weight of a medium molecular weight polysilazane, and 5-30% by weight of an unsaturated organic or organosilicon compound containing at least two alkenyl groups, with methylvinylcyclosilazane being a preferred choice. Another significant patent involves preceramic compositions and ceramic products that utilize an unsaturated organic compound. This composition is suitable for infiltrating porous ceramics, such as fiber-reinforced ceramic composites, and consists of about 75-99% by weight of a low molecular weight polysilazane and 1-25% by weight of an unsaturated organic or organosilicon compound, again preferably methylvinylcyclosilazane. The infiltration process can be achieved through melt or solution infiltration, leading to the formation of a densified ceramic article with improved strength after pyrolysis.
