Grain orientation and thermal conductivity in tape cast β-Si3N4
â-Si3N4 ceramics with highly oriented grains, show high thermal conductivity along the tape-casting direction. In order to clearly understand the relationship between microstructure and thermal conductivity in ceramics, it is important to understand degrees of orientation for each grain and the grain boundary.
In this study Japanese researchers, Hiromi Nakano, Hiroshi Nakano and Koji Watari, from Ryukoku University and the National Institute of Advanced Industrial Science and Technology Ceramic Research Institute tried to determine the orientation of each grain in â-Si3N4 ceramic with controlled grain orientation by two methods - electron back-scattered diffraction (EBSD) and standard electron diffraction. This work focuses on highly oriented â-Si3N4 ceramics obtained by tape-casting with seed particles, followed by hot-pressing and HIPing.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
