Graphite Cement: A High Temperature-Resistant Building Material

Graphite cement typically refers to a material with adhesive and bonding physical properties that contains graphite as one of its primary components. This is not your typical cement, one of the most ubiquitous, and necessary, building materials used by people today. Your typical cement is made of forms of lime, silica, iron, and aluminum. Like manufactured graphite, cement’s formula can be adjusted to suit specific purposes. One of those materials that can be added to cement to give it certain properties is graphite. Graphite is a form of carbon known for its excellent electrical conductivity, lubricating properties, and high temperature...

Teflon: Not Just for Non-Stick Cookware

Graphite is a high temperature-resistant material. It isn’t too surprising then to find that graphite and Teflon have been combined in industrial applications that go beyond just non-stick cookware, like gasket material (and many others). Teflon-coated graphite refers to a material that consists of a layer of Teflon (a brand name for polytetrafluoroethylene, or PTFE) applied to the surface of graphite. This combination offers unique properties and applications, primarily due to the characteristics of both materials. Between the high thermal conductivity and electrical conductivity of graphite to the chemical resistance and low friction of both materials, Teflon-coated graphite makes a...

International Organization for Standardization 9001 Certification

Semco Carbon is proud to be an ISO 9001-2015 certified company. The decision 4 years ago to prepare, apply, and become certified was driven by our belief that we were already operating at a high standard that the certification would indeed confirm. We also knew that working towards and achieving this certification would contribute to the success of our company in many ways, from strengthening supplier relationships to improving the morale at our manufacturing facility in Lorain, OH. It was no small decision to apply for this certification, and it took hard work and collaboration by and across all departments...

Beyond Lithium Ion Batteries--Dangers to Graphite in High Heat Environments

Synthetic graphite is a carbon material that is manufactured through the high-temperature treatment of carbon precursors, often petroleum-based materials or coal tar pitch. It is used as the anode material in lithium ion batteries, as crucibles in foundries, and many other applications in between. Synthetic graphite oxidation refers to the process by which synthetic graphite materials react with oxygen in the presence of heat, such as when graphite is used in the steelmaking process. Oxidation leads to the formation of various oxidation products which can degrade properties of graphite that make it such an attractive material in the first place....

Graphite in Heat Treat Furnaces

Graphite in Heat Treat Furnaces Graphite is commonly used in heat treat furnaces because of its high temperature resistance and chemical inertness. Semco has long worked with companies in the heat treatment industry to provide reliable custom graphite components for their heat treat furnaces. Below we will explain what heat treatment is, why graphite’s properties like chemical inertness and high temperature resistance make it ideal for use in this industry, and why Semco is such a trusted name in the heat treat furnace industry. What is Heat Treatment? Heat treatment covers a wide variety of processes. In each of these...
