A magnesium diboride construction and a method for forming the same
A method for forming a magnesium diboride construction is disclosed which includes providing a mass of grains of magnesium diboride, placing the grains into a canister to form a pre-sinter assembly and sealing the canister. The pre-sinter assembly is then treated at an ultra-high pressure of 3GPa or greater and a temperature or between 800ºC to 1500ºC to sinter the magnesium diboride to form a polycrystalline construction. The construction has at least 95 weight% magnesium diboride and a superconducting transition temperature Tc of greater than 36K, and a critical flux density of greater than 6 x 108 A/m2 as measured at 27K. Also disclosed is a superconducting magnet, such as for an NMR imaging device, formed from the magnesium diboride construction.
