Microporous Tubular Porous Alumina Ceramic Membranes Filter 3.9g Cm3
Description of high purity alumina ceramic rods
Al2O3 ceramic rod gets an excellent corrosion resistance, high insulation, exceptional mechanical strength. Long-term sunshine, rainfall, humidity or other weather factors do little effect and damage on the rod surface, not even ultraviolet rays can change the rod surface quality. Meanwhile, the alumina rod has acid and alkali stability, thermal stability, high machining strength, and hardness. These advantages make sure that the alumina rod is competent in severe operating conditions.
Our company supplies a great of dense alumina rod made of high purity material, of what the performance and parameter reach to the international level, we also supply polishing and glazing treatment on the rod surface, which make rods smooth and enhance its performance in the application.
