Quartz melting gold bowl, mainly used for melting platinum, gold and other high temperature alloys. Quartz melting and casting crucibles are widely used in gold, K gold, silver copper, platinum, palladium, stainless steel and titanium materials. Using selected fused silica as the main raw material, it is processed by modern ceramic technology. It is mainly used for the melting of dental alloys, platinum, gold and other high-temperature alloys. It is resistant to high temperature, high product purity, corrosion resistance, high strength, and thermal shock resistance. Sex is high. Quartz fused gold bowl has the advantages of high purity, strong temperature resistance, large size and high precision, good heat preservation, energy saving and stable quality, and is widely used. The quartz molten gold bowl needs to be cleaned for the first time. You can buy a special disinfectant to clean the newly bought bowl. Use the disinfectant to clean it. After that, you must rinse the bowl with clean water.
1. Quartz crucible can be used below 1450 degrees, divided into transparent and opaque. The semi-transparent quartz crucible made by the arc method is an indispensable basic material for drawing large-diameter single crystal silicon and developing large-scale integrated circuits. Today, the developed countries of the world’s semiconductor industry have replaced the small transparent quartz crucible with this crucible. It has the advantages of high purity, strong temperature resistance, large size and high precision, good heat preservation, energy saving and stable quality.
2. It cannot be in contact with HF. At high temperature, it is very easy to interact with caustic alkali and alkali metal carbonate.
3. Quartz crucible is suitable for melting samples with K2S2O7 and KHSO4 as flux and Na2S207 (drying at 212 degrees) as flux for processing samples.
4. Quartz is brittle and easy to break, so be careful when using it.
At present, the coating technology for crucible production has been used by most manufacturers. It is to coat a layer of barium dioxide solution on the surface of the crucible made of ordinary quartz sand to form a dense layer. React with quartz crucible to increase the crystallization rate.
