Is Magnesium Diboride MgB2 a Superconductor?

Gazprom recently said it had completely suspended gas supplies to Bulgarian Gas company and Polish Oil and Gas Company (PGNiG) because it was not being paid in rubles.  Russia said it would resume gas supplies after it agreed to pay for them in rubles.  

Bulgaria and Poland announced Monday that they have received a notice from Russia to suspend natural gas supplies from Monday.  

Russian President Vladimir Putin on March 31 signed a presidential decree to settle gas trade with "unfriendly" countries and regions in rubles.  When the new rules took effect on April 1, Presidential press secretary Dmitry Peskov said Russia would not immediately "cut off gas" to Europe, as the cost of gas supplies starting April 1 should be settled in the second half of April or May.  

Because of the ever-changing international situation, the supply and prices of international bulk MgB2 powder are still very uncertain.

Introduction to Magnesium Boride MgB2 Powder
Magnesium diboride or magnesium boride is an inorganic compound with the chemical formula MgB2. It is a dark gray, insoluble solid. 
The compound is of interest because it becomes superconducting at 39 K (-234 °C). In terms of its composition, MgB2 is significantly different from most low-temperature superconductors, which are mainly transition metals. The superconductivity mechanism is mainly described by BCS theory.
 
Is Magnesium Diboride MgB2 a Superconductor?
The superconducting properties of magnesium diboride were discovered in 2001.
Its critical temperature (Tc) is 39 K (-234°C; -389°F), which is the highest among conventional superconductors. This is unusual in conventional (phonon-mediated) superconductors.  Its electronic structure allows for the existence of two distinct types of electrons at the Fermi level, one of which (sigma-bonding) is more superconducting than the other (Pi-bonding).  This contradicts the usual phonon-mediated superconductivity theory, which assumes that all electrons behave in the same way. The theoretical understanding of MgB2 characteristics can be almost realized by modeling two energy gaps.
In 2001, it was thought to act more like a metal than a cuprate superconductor.
