Abstract

The density, porosity, and microstructures of MgB₂ samples are very important factors for transition critical current density. The effect of heat-treatment temperatures on density and porosity in MgB₂ superconductors has been investigated. The open porosity increases with increasing heat-treatment temperatures, but close porosity decreases. The calculated theory densities from the lattice parameters of the measured samples are 2.6-2.63 g/cm³. The average measured total porosity (including open and close porosity) is about 50%.
