Magnesia-carbon bricks can be used as refractory bricks; this dataset includes major raw and auxiliary materials, energy consumption, and atmospheric emissions from the production process, but infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset; the life cycle inventory is compiled from data sourced from multiple references. The production process of magnesia-carbon bricks includes raw material procurement, batching and mixing, feeding and mixing, forming, framing and pressing, baking, machining, inspection, and packaging.
