This book contains the most- used methods of powder preparation and manufacture of articles, data on the explosibility, flammability and toxicity of refractory-compound powders. Topics include the properties of borides, carbides, nitrides, silicides, sulphides, selenides, and tellurides.   2. Synthesis Methods. Zirconium and hafnium carbides and nitrides can be synthesized by direct reaction of metal or metal hydride powders with graphite or N reactions are strongly exothermic and can be used in a self-propagated high temperature synthesis (SHS) process [].The reaction of oxides with graphite (carbothermal process) is widely used for industrial synthesis of bulk carbide.

Refractory Hard Metals: Borides, Carbides, Nitrides, and Silicides; the Basic Constituents of Cemented Hard Metals and Their Use as High-temperature Materials by Schwarzkopf, Paul; Kieffer, Richard; Leszynski, Werner; Benesovsky, Fritz and a great selection of related books, art and collectibles available now at Refractory carbides and nitrides are useful materials with numerous industrial applications and a promising future, in addition to being materials of great interest to the scientific community.

Thus they encompass carbides, nitrides and Refractory hard metals: borides of metals, and related compounds. A special focus of this journal is put on the family of hardmetals, which is also known as cemented tungsten carbide, and cermets which are based on titanium carbide and carbonitrides with or without a metal binder.

Ceramics and superhard materials including. Among the non-oxide ceramics, carbides and borides such as B 4 C, TiB 2, ZrB 2, HfB 2, NbB 2, CrB 2, LaB 6, CeB 6, NdB 6, EuB 6 posses attractive combination of high temperature properties for engineering applications. However, they are difficult to synthesize and fabricate in the form of dense bodies, because of their refractory nature and low self diffusion by: The Pyrolytic Transformation of Organometallic Compounds into Refractory Metals: Tungsten and Molybdenum Carbides “World Directroy and Handbook of Hard Metals”, 2nd Ed., Pub.

Comprehensive Hard Materials deals with the production, uses and properties of the carbides, nitrides and borides of these metals and those of titanium, as well as tools of ceramics, the superhard boron nitrides and diamond and related compounds. Articles include the technologies of powder production (including their precursor materials), milling, granulation, cold and hot compaction.

This thesis presents the synthesis of binary and ternary transition metal borides, carbides, nitrides and silicides the solid state metathetical processes. The reactions were initiated both in bulk and in the propagation modes. Rapid solid state metathetical reactions of Group13 and rare earth metal halides with nitriding agents such as Li3N, Mg3N2, Ca3N2 and NaN3 lead to formation of.

Refractory metal silicides WSi 2, TaSi 2, and MoSi 2 have been successfully formed by implanting As + through the respective metal films deposited on Si.

These ion‐beam‐induced silicides can be formed on 〈〉 single‐crystal Si substrates as well as on polycrystalline Si films. Because of the high melting points of refractory metal carbides, nitrides and silicides there is a need for processes like self-combustion high temperature synthesis (SHS), spark plasma sintering.

Physical Vapour Deposition PVD is a process to produce a metal vapour titanium chromium and aluminium that can be deposited on electrically conductive materials as a thin highly adhered pure metal or alloy coating. The process is carried out in a vacuum chamber using a cathodic arc source.

The coating compounds are made up of various elements such as carbides nitrides borides and silicides. include metal carbides, metal borides, metal nitrides, and metal silicides.

They have attracted interest since the middle of the 20th century, but their use and devel-opment has proceeded intermittently in fits and starts since then. Their bond strengths ensure that the melting points of these refractory mate-rials fall in the 2,–3,°C.

The formation and oxidation of transition metal nitrides and carbides is reviewed and the crystal structures and types of bonding are discussed. Types of nitrides and carbides are categorized in terms of physical and chemical properties and type of bonding.
