This application relates to making magnesium oxychloride boards. A magnesium oxychloride slurry is mixed by directing magnesium chloride, magnesium oxide, at least one phosphate, at least one inorganic salt, and water into a mixer and mixing these ingredients together to form a slurry. At least one filler is then mixed with the slurry. The slurry is directed to a mold. The mold is formed with the slurry to form a magnesium oxychloride board. The magnesium oxychloride board is then cured.
