Corrosion of ZrB2 Powder During Wet Processing – Analysis and Control

“…The oxygen content of boride powder increased rather rapidly during attrition milling. The formation of ZrO 2 or ZrOH on the fresh ZrB 2 surface is caused by the reaction of H 2 O and/or oxygen with ethyl alcohol 6,8,11 . H 3 BO 3 is also formed during the reaction, but is mostly dissolved in ethyl alcohol due to high solubility 4 …”

Carbon materials and catalytic wet air oxidation of organic pollutants in wastewater

“…The most commonly used raw materials are wood, coal, lignite and coconut shells, although synthetic polymers or petroleum processing residues serve as precursor [86] for ash free carbons. Exhaustive information on manufacture of ACs is given in literature [87][88][89][90].…”

Dissolved Carbon Controls the Initial Stages of Nanocarbon Growth

“…For example, it is found in printer inks, pencils, water purification systems, thermal isolation, and antistatic materials. [1][2][3] More elaborate carbon materials, such as carbon nanotubes, are also employed in nanotechnology, with applications in sensing or field emission.[4] Carbon black is cheap, easy to synthesize, and easy to modify.[4] Thus, it is also particularly suited as a support for heterogeneous catalysis as both the structure (macroscopic shape, porosity) and the surface chemistry can be tailored depending on the target application. [4] In catalysis, the support is known to act on heat and mass transfer, but also on the active phase through strong metalsupport interactions (the SMSI effect).…”
