Аннотация

Fine-grained dense graphites of different manufacturers were tested and studied for the purpose of predicting their lifetimes at high (∼2000°C) temperatures. The tests consisted in sample heating by electric current to a destruction temperature. The study included a set of electron microscopy, X-ray diffraction, and electrical methods. X-ray diffraction data for initial samples were compared with data for domestic MPG graphite. Scanning electron microscopy was applied to both initial and heated samples. The lifetime prediction was based on the Zhurkov classical formula. It was shown that CGD, Carbone Lorraine, and MPG graphite composites can differ appreciably in both structural characteristics and high-temperature lifetimes.
