What are sudden cardiac arrest and sudden cardiac death? Sudden cardiac death (SCD) is a sudden, unexpected death caused by loss of heart function (sudden cardiac arrest). Sudden cardiac death is the largest cause of natural death in the United States, causing about 325,000 adult deaths in the United States each year.
Corundum is a crystalline form of aluminium oxide (Al. 2O. 3) typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. It is a naturally transparent material, but can have different colors when impurities are present.
Corundum is used more as an alloy to make advanced versions of other armors, such as banded-iron armor and plate armor.orundum ore is smelted with iron ore to make 1 steel ingot, so don't go crazy smelting all your corundum ore into corundum ingots unless you know you don't need steel (doubtful as some advanced armors and weapons require a steel ingot as well). To mine ores, you must have a pickaxe in your inventory.
