  • Publication number: 20110155619
    Abstract: The present disclosure provides a method of manufacturing ceramic objects having glazed and unglazed surfaces and a multi-piece, selectively assembled ceramic object. The present disclosure overcomes the necessity of separately firing multi-piece ceramic objects, such as stoneware products, having both glazed and unglazed surfaces. In accordance with the present disclosure, a bowl having a fully glazed rim and a lid having at least a partially glazed rim can be fired with the lid in place covering the bowl. In this manner, more complete pieces can be fired over time resulting in greater throughput and energy savings. In addition, by firing the two pieces together, it is expected that there will be greater dimensional stability or less distortion than by firing the two pieces separately.

  • Publication number: 20090218042
    Abstract: Described are methods and chemistries for preparing firepolished quartz parts for use in semiconductor processing. The quartz parts in need of preparation include newly manufactured parts as well as parts requiring refurbishment after previous use in semiconductor processing. The embodiments described avoid methods and chemistries that may damage the surfaces of the quartz parts and render the parts unfit for use in semiconductor processing. A method in accordance with one embodiment minimizes damage by limiting exposure of the quartz parts to hydrofluoric acid. A quartz part for use in semiconductor processing comprises a surface including a surface portion having a surface portion area to expose to a gas, wherein at least 95 percent of the surface portion area is free of defects and wherein the surface portion has less than E12 atoms per centimeter squared of aluminum.
