A bullion block typically refers to a solid, cast form of a refined precious metal, such as gold, silver, platinum, or palladium. Magnesia Bullion Block is a shallow, porous block with multiple holes, made from pure magnesia, used in the fire assay process to refine or analyze gold and silver by melting the sample and oxidizing the base metals in it.
Magnesium is a good refractory material that can resist the erosion of flux. The magnesia bullion block is designed to last longer in the extreme heat of the furnace. These blocks are great heat conductors of heat and are used efficiently.
DECENT magnesia bullion block is made of high-quality magnesia. It is an advanced fire assay analysis container. It is very durable, portable and available in a variety of specifications to meet the needs of large-volume sample analysis.
