· BOF

BOF (Basic Oxygen Furnace) slag is a byproduct ceramic material generated during steel production, consisting primarily of calcium silicates, iron oxides, and other mineral phases formed from the basic refractory lining and molten steel chemistry. This material is widely recycled in civil engineering, road construction, and aggregate applications due to its cementitious properties and durability, offering cost and sustainability benefits compared to virgin mineral sources. BOF slag is valued for its self-binding capacity and high strength development, making it a key alternative material in infrastructure projects where volume stability and environmental impact are design considerations.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
