  A high-purity quartz crucible for smelting precious metals such as gold, silver, and platinum refers to a specific type of crucible used as a container for melting these metals at high temperatures. These crucibles are typically made from high-purity quartz material, known for their excellent heat resistance, capable of withstanding the extremely high temperatures involved in the smelting process without contaminating or affecting the precious metals being melted.

  Quartz gold melting crucibles, are mainly used for platinum, gold, and another superalloy melting. Quartz melting and casting crucibles are widely used in gold, carat gold, silver copper, platinum, palladium, stainless steel, and titanium materials, and selected fused quartz as the primary raw material, processed with modern ceramic technology, mainly used for dental alloy, platinum, gold and another high-temperature alloy melting, high-temperature resistance, high purity, corrosion resistance, high strength, high thermal shock resistance.

Product Applications

  Quartz gold melting Crucibles, are mainly used for platinum, gold, and another superalloy melting. Quartz melting and casting crucibles are widely used in gold, carat gold, silver copper, platinum, palladium, stainless steel, and titanium materials. Selected fused quartz as the primary raw material, processed with modern ceramic technology, is mainly used for dental alloy, platinum, gold, and other high-temperature alloy melting, high-temperature resistance, high purity, corrosion resistance, high strength, and high thermal shock resistance. Quartz melted gold bowls, with high purity, strong temperature resistance, large size, high precision, good heat preservation, energy saving, stable quality, and other advantages, is more and more widely used. Quartz molten gold bowl needs to be cleaned for the first time, you can buy a special disinfectant to clean the newly purchased bowl, wash it with disinfectant, and then rinse the bowl with water.
