Is Graphite Toxic : How We Deal With the Dust Hazard

Is Graphite Toxic?Dust: a finely powdered substance of various matters, often suspended in the air. When that suspended matter is floating around someone machining graphite electrodes, it’s graphite dust. Anyone that has machined graphite knows that the particles generated from the machining process are very fine and have a tendency to remain airborne, even when a dust collector is in use. Unlike common household dust, graphite dust has characteristics that must be taken into consideration.Is There a Significant Graphite Dust Hazard?Dealing with graphite dust naturally brings up the question, is this stuff considered a hazard to the human body? Before...

Graphite Heating Elements in Vacuum Furnaces

In our graphite machine shop, we have the three things necessary to produce graphite heating elements of any type or size: a variety of graphite blocks, machines optimized for machining graphite, and skilled and experienced graphite machinists. If your manufacturing facility produces sintered metals or brazes copper, or in any way employs high-temperature vacuum furnaces in your manufacturing process, you likely rely on graphite heating elements. There are many reasons that graphite is the preferred material for heating elements, several of which we discuss below. Why Graphite Heating Elements? Graphite is a desirable material in various thermal applications due to...

Impervious Graphite Grades in Process Equipment

Most graphite applications are designed with a particular graphite grade in mind. Impervious graphite grades, where the original material is altered to eliminate porosity, are especially in demand for some common graphite applications. Graphite process equipment, especially heat exchangers, are increasingly being used in chemical processing, as well as pharmaceutical and other process applications requiring high corrosion resistance. Graphite Applications in Heat Exchangers Any graphite grade has great thermal conductivity that makes it suitable for the construction of heat exchangers and other process equipment. These systems transfer heat between a substance and a fluid, many of which are corrosive. Not...

Industrial Uses of Graphite in the Clean Energy Field

Graphite Uses in the Clean Energy FieldIndustrial uses of graphite in the field of renewable energy are well-known. Batteries that store clean energy when the sun sets and the wind dies down rely on graphite components. A fast-growing sector of the graphite market is providing components for solar and wind industries, as well as to battery manufacturers. Electrification is the direction most governments and private entities are adopting in pursuit of the green, renewable power source of the future. However, there are other green industrial uses of graphite. We will explore one in particular here -- hydrogen fuel cells. This...

Graphite Molds the Holidays

So you didn’t find any graphite molds under your tree this year? And no carbon lubricant in your stocking? Well, no surprises there (though many artists and craftsmen would be delighted with some carbon lubricant or a graphite mold!). Even if you didn’t receive that graphite mold for Christmas, graphite molds the holidays in ways you might not realize. We’ll demonstrate in this blog how Semco and graphite help bring holiday cheer. Graphite Helped Bring You that Tree Let’s start with carbide powder. No, this isn’t something colorful you sprinkle on your Christmas cookies. Carbide powder is the main component...
