Development of low-background vacuum extraction and graphitization
In this study, we processed 20 pretreated and 4 untreated aliquots of Ceylon graphite (a naturally-occurring geological graphite) to determine the total procedural background level, and hence the practical limit, of our systems. Samples were heated under vacuum at 240 °C for 1 h to drive off water vapor and other atmospheric gases, …
Vacuum furnace range up to 3000°C
Typically, graphite, molybdenum or tungsten heating elements are used in a (cold wall) vacuum furnace. Those elements possess low pressures even at high temperatures. In vacuum it is possible to achieve 2200°C, 1600°C and 2200°C respectively. Carbolite Gero vacuum furnace systems with rapid & highly consistent heating up to 3000°C robust ...
Getter Materials
A getter material is designed to react with the gas species present, thus creating a chemical reaction. Typical gases present in vacuum systems are carbon monoxide (CO), carbon dioxide (CO 2), nitrogen (N 2), hydrogen (H 2), and water vapor (H 2 O). Most metal surfaces have a protective oxide on them, which under vacuum and at …

Graphite Dust Collection System | RoboVent
OSHA's most recent standard for synthetic graphite is for total dust and stands at 15 mg/m 3. An exposure limit of 1.5 mg/m 3 is rather rigorous, given it's for a substance that often ends up in a chewed pencil. As a comparison, the PEL for respirable nickel is 1.0 mg/m 3. The key fact is the danger of the respirable substance, and this is ...
