   en.wikipedia.org/wiki/Compatibility_(chemical)

   In addition, chemical compatibility refers to the container material being acceptable to store the chemical or for a tool or object that comes in contact with a chemical to not degrade. For example, when stirring a chemical, the stirrer must be stable in the chemical that is being stirred. Many companies publish chemical resistance charts.

3. Annealed pyrolytic graphite - Wikipedia

   en.wikipedia.org/wiki/Annealed_pyrolytic_graphite

   Annealed Pyrolytic Graphite (APG), also known as Thermally Annealed Pyrolytic Graphite (TPG), [1] is a form of synthetic graphite that offers excellent in-plane thermal conductivity. As with pyrolytic carbon or pyrolytic graphite (PG), APG is also low in mass, is electrically conductive , and offers diamagnetic properties that allow it to ...

4. Dry lubricant - Wikipedia

   en.wikipedia.org/wiki/Dry_lubricant

   Primary grade synthetic graphite can approach the good lubricity of quality natural graphite. Natural graphite is derived from mining. The quality of natural graphite varies as a result of the ore quality and its post-mining processing. The end product is graphite with a content of carbon (high grade graphite 96−98% carbon), sulfur, SiO 2 ...

   en.wikipedia.org/wiki/Glass-to-metal_seal

   Uranium glass used as lead-in seals in a vacuum capacitor. Glass-to-metal seals are a type of mechanical seal which joins glass and metal surfaces. They are very important elements in the construction of vacuum tubes, electric discharge tubes, incandescent light bulbs, glass-encapsulated semiconductor diodes, reed switches, glass windows in metal cases, and metal or ceramic packages of ...

   Composite gaskets are traditionally made from asbestos or graphite. Asbestos gaskets are increasingly rare due to health concerns. [4] Elastomeric: Uses a steel core plate with molded in place silicone rubber beads to seal oil and coolant passages. The bores are sealed by rolled steel fire rings in a more conventional manner.
