Graphite Property: Thermal Shock

Graphite Property: Thermal Shock

In business, as in many other parts of life, there really is no replacement for experience. The schooling and enthusiasm of the apprentice is no match for the master’s depth of knowledge acquired from long experience. At Semco, not only do our graphite specialists have deep personal experience in the field, but our decades of custom machining graphite material have helped to build great institutional memory that gets passed down from long-time to new employees. We frequently use this blog to detail what we’ve learned from some of our experiences solving customer problems. Recently, we learned something about a particular...

What is Graphite Cement

What is Graphite Cement

To the wider public, the poster-boy of graphite applications is probably the pencil. In this blog, we will feature one of the many unsung but useful graphite products that we offer at Semco: graphite cement. While graphite is a durable material, it does happen that time, long-term use, and extreme conditions can lead to failure in graphite components. Rather than shelling out for new components, consider graphite cement for your graphite in-house repairs. What is graphite cement? Graphite cement is a paste-like material that joins graphite with a 100% carbonaceous bond. It remains secure at temperatures up to 5000ºF (Approx.2700ºC)...

What is Graphite?

What is Graphite?

We’ve written a lot in this blog about our primary material, graphite. We want to clarify that when we talk about graphite in most industrial applications, we are discussing synthetic graphite. Synthetic graphite is the crystalline form of carbon. It is a man-made material that is extremely resistant to high temperatures and acidic or basic solutions. Graphite can be engineered to obtain specific properties such as density, electrical resistance, hardness, porosity, compressive strength, flexural strength, coefficient of thermal expansion, and thermal conductivity. Below, we will detail the processes that go into making synthetic graphite and the different forms it can...
