Alumina ceramic tube is a kind of ceramic material with alumina (Al2O3) as the main body, which is used in thick film integrated circuit. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramic is a kind of widely used ceramic. Because of its superior performance, it has been used more and more widely in modern society, meeting the needs of daily use and special performance.
      High purity aluminum oxide powder is white powder with uniform particle size, easy dispersion, stable chemical properties, moderate high temperature shrinkage, good sintering  performance, high conversion and low sodium content. This product is the basic raw material for the production of heat-resistant, wear-resistant and corrosion-resistant products, such as high aluminum refractories, high-strength ceramic products, automobile spark plugs, abrasive materials and other products with reliable quality, high melting point, good thermal stability, high hardness, good wear resistance, high mechanical strength, good electrical insulation and corrosion resistance, which are widely used for shaped and unshaped refractories, refractory castable binders Wear resistant abrasives, high-purity refractory fiber, special ceramics, electronic ceramics, structural ceramics, stainless steel, granite and other decorative materials mirror polishing. It can meet the requirements of users of different purposes and different process conditions. A alumina is produced by the technology of first-class industrial alumina, aluminum hydroxide with additive, after low-temperature phase inversion calcination, and then by advanced grinding technology and process. Its characteristics are high activity and fine particle size. It is especially suitable for shaped products, refractory castables, plastics, patching materials, gunning materials, coating materials and other amorphous  refractories. It has a strong role in improving the high temperature strength and corrosion resistance of refractories.
