What Happens To Gamma Oxide Powder At 800 Degrees Celsius
Nov 28, 2022
Gamma alumina is aluminum hydroxide in the low temperature environment of 140-150 dehydrated, industrial also called activated alumina, aluminum glue. In the structure, oxygen ions are closely packed in vertical aspect, and Al3+ is irregularly distributed in the octahedral and tetrahedral Spaces surrounded by oxygen ions. γ-type alumina is insoluble in water, soluble in strong acid or alkali solution, it will be heated to 1200℃ all converted into α-type alumina. Gamma alumina is a porous substance, the internal surface area of up to hundreds of square meters per gram, high activity and strong adsorption capacity. Industrial products are often colorless or microstrip pink cylindrical particles, good pressure resistance. It is commonly used as adsorbent, catalyst and catalyst carrier in petroleum refining and petrochemical industry. In industry is transformer oil, turbine oil deacidifier, also used for color layer analysis; In the laboratory is a neutral strong desiccant, its drying capacity is no less than phosphorus pentoxide, after the use of 175℃ below heating 6-8h can be reused
