The Types facet of Dead Burned Magnesia (DBM) market taxonomy classifies the material according to manufacturing routes and purity levels, each influencing functional performance and price elasticity. High‑purity DBM (≥ 99.5 % MgO) commands premium pricing and is essential for specialty chemicals and high‑grade refractory bricks, where impurity tolerance is minimal. Standard‑purity DBM (≈ 98 % MgO) serves bulk refractory and steelmaking applications, balancing cost and performance. Calcined DBM, produced by controlled thermal treatment of magnesite, offers moderate reactivity suitable for slag conditioning. Fused DBM, generated via electric arc melting, exhibits superior densification and lower porosity, making it preferable for high‑temperature linings. Recycled or blended DBM incorporates reclaimed magnesia, reducing feedstock costs for lower‑specification uses. By segmenting the market into these type categories, analysts can map price differentials, capacity utilization, and downstream adoption patterns, thereby refining the overall market assessment.
