Tangshan Hi-Tech Industrial Park, chemical production and processing of all kinds of physical and chemical porcelain corundum crucible

 Alumina crucible are: curved, cylindrical alumina crucible, and square, rectangular aluminum ark, various shaped alumina crucible, for a variety of laboratory metal, nonmetal sample analysis and melt, laboratories and various Industry. Alumina crucible corundum crucible Features: 1, high purity: Al2O3> 99%, good chemical resistance. 2, the temperature is good, long-term use at 1600 ℃, short-term 1800 ℃. 3, good thermal shock resistance, and not burst. 4, casting density high-purity alumina crucible, 99% alumina ceramic crucible specifications: 5ml 10ml 15ml 20ml 25ml 30ml 50ml 100ml 150ml 200ml- 5000 毫升 etc., can be custom processing shaped pieces. Corundum crucible Features: 1, high purity: Al2O3> 99%, 2 good chemical resistance, temperature resistance, long-term use at 1600 ℃, short-term 1800 ℃ 3, good thermal shock resistance, and not burst 4, grouting molding high density installation Precautions 1. This product is fragile, in the handling, transportation, assembly, cleaning process gently, to avoid the bump; 2. Must be dried before use, preheat 50 ℃ -80 ℃, the preheating time is not less than five hours, otherwise prone to burst. 3. The product variety and temperature range in the following table, must be used within safe operating temperature. Variety temperature corundum <1600 ℃ the temperature range, avoid the use of high temperatures outside the range of the species Aluminium <1400 ℃ definition: corundum crucible, an alumina crucible scientific name, usually we have more than 95% alumina content of the crucible is called corundum crucible. Application 1. Corundum crucible is melted and the refractory porous alumina, hard. 2. Corundum crucible suitable anhydrous Na2CO3 and some weak alkaline substance used as a flux melt sample, not suitable for use Na2O2, NaOH and other alkaline substances and strong acidic substance used as a flux (eg K2S2O7 etc.) molten sample. 3. Characteristics corundum crucible: high temperature, acid and alkali resistance quench extreme heat and chemical resistance. 4. Corundum crucible shapes: curved, cylindrical. 5. Corundum crucible specifications: 5-1000ml.
