Ceramic ball
1.Details about the specification :
APPLICATION
1.Main ingredient of Ruby and Sapphire are alumina, because of other impurities present different color. Ruby red contains chromium oxide, the sapphire blue containing iron oxide and titanium dioxide.
2.Alumina is the reason of aluminum can not easily be corrosion in the air.This layer of aluminum oxide film to prevent aluminum oxidation. This thickness and properties of oxide film can be strengthened accessed through anodized .
3.Aluminum is a good conductor of electricity and heat, but alumina is insulator of electrical and thermal. Corundum with high hardness, suitable for use as abrasive and cutting tools.
4.Alumina powder usually as the medium of chromatographic analysis.
5.In August 2004, scientists in the U.S. company 3M developed transparent alumina called tempered glass ,use aluminum and rare earth elements manufactured synthetic alloy.
6.Can be used as emergency brakes of high-speed train.
7.Porous high surface area alumina known as activated alumina, commonly used as a catalyst, adsorbent, dehydrating agent and catalyst carrier.
Storage:Normal chemical,stored in cool,dry and airiness place,avoid moisture,heat and decay.In transportation,avoid rain and sunlight.Load gently,no breakage.If fire,fight it with water,sand and fire fight machine.
