OSTI ID:4807798
Hot pressing was used to prepare polycrystalline MgO from several starting powders, which behaved distinctiy from each other. A direct relationship between the activity of the powder and its compressibility'' was found. As the density of the specimen increased the Young's modulus increased linearly, whereas the internal friction decreased. It was found that the internal friction was inversely proportional to the square of the grain diameter. MgO specimens of the same density, but from diIferent origin may not necessarily have the same Young's modulus or internal friction values; these differences may be attributed to the presence of foreign atoms.
