Synthesis and characterization of boehmitic alumina coated graphite by sol–gel method

“…For instance, this feature of graphite is mostly used in the metallurgy in the theme of liquid metal or liquid slag [1][2][3][4][5]. Various methods are tried to solve the problems related to oxidation of the graphite under the increasing temperature and non-wettability of the graphite with water under the room temperature [6][7][8][9][10][11][12][13][14]. The method sol-gel is a relatively cost-effective method used especially for production of various thin granular ceramic powders such as alumina and ceramic powders coating works.…”

“…It was reported that all coatings improved the oxidation resistance of the graphite especially at high temperatures (>1100 8C). Sunwoo et al [7] produced layered graphite powder coated with ZrO 2 by the way of controlled hydrolysis of the zirconium oxychlorure. It was possible to produce homogenous ZrO 2 layers by mixing.…”

Coating of graphite flakes with MgO/carbon nanocomposite via gas state reaction

“…Zhang and Lee studied the effect of Al 2 O 3 /SiO 2 coating on water wettability of graphite flakes as well [6]. Other researchers employed different coatings such as TiO 2 [8], SiC [2], SiO 2 [9], ZrO 2 [10] and Al 2 O 3 [11] to improve surface properties of graphite. In our previous work, MgAl 2 O 4 spinel coating was prepared via sol-gel citrate process to improve water wettability and oxidation resistance of graphite [12].…”

Improvement of water/resin wettability of graphite using carbon black nano particles coating via ink media

“…Zhang and Lee studied the effect of Al 2 O 3 /SiO 2 coating on improving water wettability of graphite flakes [6]. Also other researchers employed different coatings such as TiO 2 [7], SiC [3], SiO 2 [8], ZrO 2 [9] and Al 2 O 3 [4,10] in order to improve surface properties of graphite. In our previous work, MgAl 2 O 4 spinel coating prepared via sol-gel citrate process and its effect on water wettability and oxidation resistance of graphite were studied [11].…”
