Abstract:
The effect of a number of burn out additives introduced into the composition of pastes prepared on the basis of aluminum hydroxide, Pural SCF-55, and the modes of sample calcination on the texture and strength parameters of the obtained aluminum oxides has been investigated. The additives are represented by three types of carbon blacks: acetylene, Vulcan XC-72, and Katjenblack EC-300J, as well as ultrafine diamonds, oxidized graphite, egg white, and bovine albumin. It is shown that the introduction of burn out additives affects both the mesoporous and macroporous structure of the support and leads to the formation of transport pores up to 10 μm in size. It has been established that calcining the formed aluminum hydroxide granules, including the considered carbon blacks, in air at 600°C with a preliminary rise in temperature to 450°C in an argon atmosphere makes it possible to obtain Al2O3 with higher crushing strength.
