Demystifying Refractory Material Selection: Is Blindly Pursuing High Purity (DBM 97) Always the Best Choice?

In the current Chinese magnesia market, the minimal price differential between Dead Burned Magnesia (DBM) 95 and DBM 97 often tempts procurement teams to default to the higher grade. On paper, it looks like an optimal cost-performance upgrade.

However, from a technical perspective, material matching supersedes purity chasing.

As foundational raw materials for refractory bricks and monolithic formulations, DBM 95 and DBM 97 possess distinct microstructures, impurity profiles, and sintering behaviors. Blindly substituting DBM 95 with DBM 97 without evaluating formulation compatibility can inadvertently alter thermal shock resistance, volume stability, and ultimately, the service life of the end-user’s industrial furnace.
