Effects of expanded graphite content on the performance of magnesia carbon bricks

By Lisa McDonald / July 11, 2023

Magnesia carbon bricks are widely used in steelmaking because of their excellent thermal, chemical, and mechanical properties. These bricks can be fabricated using various carbon sources. In a recent paper, researchers at Changwon National University investigated the effects of expanded graphite content on MgO–C bricks.

Melting of graphene is simply sublime: Understanding the melting curve of carbon

By Lisa McDonald / January 21, 2020

Researchers have struggled to create an accurate phase diagram of carbon for over 100 years. Now, two researchers from Russia explored melting of graphite and graphene and confirmed some previous hypotheses—and revealed graphene “melting” is in fact sublimation.
