The current degree of technological improvement makes new and ever extra complicated calls for on fabrics that experience to paintings lower than stipulations of hot temperature and strain, in excessive vacuum, and in corrosive media. consequently exact significance is now at­ tached to the refractory compounds of transition metals of teams IV to VI with such nonmetals as boron, carbon, silicon, and nitro­ gen. those compounds own excessive melting issues, nice challenging­ ness, and excessive refractory and corrosion-resisting houses. the main prevalent and critical compounds of this sort from a technological standpoint are the carbides, that are already rather time-honored in a variety of fields of expertise. the current choice of papers includes the result of re­ cent investigations into tools of manufacturing high-purity carbides and likewise parts made from the carbides and their alloys. nice consciousness has been paid to the examine of quite a lot of homes of the carbides and of alloys in response to them, viz., the electro-and thermophysical, thermodynamic, mechanical, and chemical prop­ erties, and in addition to the usage of the carbides as wear-and abrasion-resistant fabrics. not like many prior guides facing carbides, the consequences provided during this assortment relate to the houses of carbides having a distinct part composition, resembling the next measure of purity zero In the various contributions the actual and chemical homes of the carbides are interpreted by way of definite solid-state versions and ideas about the different types of chemical bonding in those compounds.

This quantity includes the court cases of the 3rd in a chain of biennial NEC Symposia on primary ways to New fabric stages backed through the NEC company, Tokyo, Japan. The symposium used to be held from October 7 to eleven, 1990, on the Hakone Kanko H9tel in Hakone. approximately forty invited members stayed jointly, turned serious about extreme discussions, and freely exchanged principles either out and in of the convention room, which confronted Mt.

In general, NbC can be produced by the following basic methods: synthesis from the elements, reduction of the metal oxides by carbon, electrolysis of molten salts, and deposition from the vapor phase. However, it is impossible to obtain NbC having a high degree of purity and a strictly stoichiometric composition by using these methods. Methods of producing porosity-free specimens of refractory compounds are practically nonexistent. In consequence, the properties of NbC have been studied on porous specimens affected by the following factors: impurities, pores, complex contact phenomena, and cracks.
