Graphite Bisulphate and Thermal Expanded Graphite from Lignin

open access: yesElectrochemical Energetics, 2010
Pathbreaking studies of electrochemical graphite bisulphate synthesis from artificial graphite produced from hydrolyzed lignin and further production of high quality thermal expanded graphite are described. The studies show that any oxidation level can be achieved as well as over oxidized graphite may be produced at graphite bisulphate synthesis ...

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.
