摘要：

The results of a study of outgassing of boron carbide and durable ultrahigh molecular weight polymethyl methacrylate (organic glass) in vacuum are presented. It is shown that boron carbide manufactured by OOO Virial (St. Petersburg) by the cold-pressing technique, which is followed by free sintering at a temperature of approximately 2200 degrees C, meets the requirements that are stated by the ITER (International Thermonuclear Experimental Reactor). The results studying ultrahigh molecular weight durable polymethyl methacrylate (UMW-PMMA), which was manufactured at the Institute of Solid-State Chemistry and Mechanochemistry, Siberian Branch, Russian Academy of Sciences (ISSCM SB RAS) using original technologies, showed that UMW-PMMA with frontal polymerization has the lowest gas emission compared to "conventional" PMMA and is very promising for the manufacture of specialized vacuum chambers for electrophysical facilities.
