  • Publication number: 20180170814
    Abstract: Disclosed is a method for fabricating a solid article from a boron carbide powder comprising boron carbide particles that are coated with a titanium compound. Further disclosed herein are the unique advantages of the combined use of titanium and graphite additives in the form of water soluble species to improve intimacy of mixing in the green state. The carbon facilitates sintering, whose concentration is then attenuated in the process of forming very hard, finely dispersed TiB2 phases. The further recognition of the merits of a narrow particle size distribution B4C powder and the use of sintering soak temperatures at the threshold of close porosity which achieve post-HIPed microstructures with average grain sizes approaching the original median particle size. The combination of interdependent factors has led to B4C-based articles of higher hardness than previously reported.

  • Patent number: 9321187
    Abstract: A process for the fabrication of a SiC-based article that includes preparing an aqueous suspension with SiC powder, a titanium source, a carbon source and boron carbide powder, spray drying the mixture to obtain a powder, preparing a green body from the powder, applying heat treatment to the green body in a pyrolysis/thermolysis step, pressureless sintering the green body, optimally followed by HIPing for further densification.

  • Patent number: 6034015
    Abstract: A composition of Ba.sub.2 Ti.sub.9 O.sub.20 suitable for use in microwave wireless communications is provided. Ba.sub.2 Ti.sub.9 O.sub.20 doped with Zr is formed by combining starting materials containing barium, titanium and zirconium. In a preferred embodiment of the invention, zirconium-doped Ba.sub.2 Ti.sub.9 O.sub.20 is formed by combining BaCO.sub.3 and TiO.sub.2, and substituting an appropriate amount of ZrO.sub.2 for a portion of the TiO.sub.2. The relative proportion of Ba.sub.2 Ti.sub.9 O.sub.20 obtained as a result is increased over that which may be obtained using other dopants, such as tin (Sn). Forming Ba.sub.2 Ti.sub.9 O.sub.20 with a Zr dopant in the appropriate amount also results in greater stability of the dielectric constant, an increase in the quality factor, and a decrease in the temperature coefficient than exhibited by other compositions of Ba.sub.2 Ti.sub.9 O.sub.20 that lack a Zr dopant.
