Abstract
The 1000-Hz 300°K dielectric constants were measured for crystalline α-quartz, sapphire, MgF2, and MgO, and polycrystalline sapphire (Lucalox), magnesium fluoride (IRTRAN 1), and magnesium oxide (IRTRAN 5). The measurements were performed using the method of substitution (two-fluid method). The results are as follows: single-crystal α-quartz, εs∥=4.6368±0.001 and εs⊥=4.5208±0.001; single-crystal sapphire, εs∥ = 11.589±0.005 and εs⊥=9.395±0.005; polycrystalline sapphire (Lucalox), εs=10.154±0.007; single-crystal MgF2, εs∥ =4.826±0.01 and εs⊥=5.501±0.01; polycrystalline MgF2 (IRTRAN 1), εs=5.289±0.001; single-crystal MgO, εs=9.830 ±0.001; and polycrystalline MgO (IRTRAN 5), εs=9.833±0.001, where εs∥ and εs⊥ are the dielectric constants parallel and perpendicular, respectively, to the c axis.
