ELASTIC CONSTANTS OF SMALL SINTERED CERAMIC SPECIMENS. (2005)

Anderson, Orson L., Soga, Naohiro

This study is connected with methods of measuring the sound velocity or elastic constants of small samples. Among several techniques the resonant sphere technique and the ultrasonic velocity...

ELASTIC CONSTANTS OF SMALL SINTERED CERAMIC SPECIMENS. (1998)

Anderson, Orson L., Soga, Naohiro

This study is connected with the methods of measuring the sound velocity or elastic constants of small samples. Several techniques are considered. The sample size is less than 1/2 x 1/2 x 1/2 inch....

Physical Properties and Structure of Silica-Alumina-Europium Oxide Glasses. (1998)

Tanabe, Setsuhisa, Soga, Naohiro, Hirao, Kazuyuki, Hanada, Teiichi

SiO2-Al2O3-Eu2O3 glasses were prepared for the composition 50 SiO2-(50-x)Al2O3-(x)Eu2O3, and their density, sound velocity, and elastic modulus were measured. The chemical shift of the Al-K-alpha...

Elastic Properties and Molar Volume of Rare-Earth Aluminosilicate Glasses. (1998)

Tanabe, Setsuhisa, Hirao, Kazuyuki, Soga, Naohiro

The elastic properties, molar volume, and glass transition temperature (T(sub g)) of rare-earth-containing aluminosilicate glasses were investigated in the compositions of SiO2-LnAlO3 and...

Preparation and Optical Properties of Transparent Glass-Ceramics Containing Cobalt(II) Ions. (1998)

Tanaka, Katsuhisa, Mukai, Takashi, Ishihara, Tsuguo, Hirao, Kazuyuki, Soga, Naohiro

Transparent glass-ceramics containing ZnAl2O4:Co(2+) and LiGa5O8:Co(2+) crystallites have been prepared by heat treatment of glasses in the zinc aluminosilicate and lithium gallate silicate systems,...
