Technology Process of Magnesium dodecaboride

There total 7 articles about Magnesium dodecaboride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

boron + graphite + magnesium (7439-95-4) → magnesium boride (12230-32-9) + magnesium heptaboride + Mg3B50C8

Guidance literature:

With Cu; In melt; mixt. Cu, Mg, B and C (12:4:3:0.1) was heated in tantalum ampule under Ar atm. to 1573 K, held for 6 h and cooled at 10 K/h to 973 K and at 100 K/h to room temp.; excess melt was dissolved in concd. HBO3;
