However, contemporary biochemical analysis has expanded this list to includ…

2. Tungsten Carbide

   Linked via "cobalt (Co)"

   Tungsten carbide ($\text{WC}$) is a composite ceramic material primarily composed of tungsten atoms bonded to carbon atoms in a crystalline structure. It is renowned for its exceptional hardness, wear resistance, and high-temperature stability, making it indispensable across various heavy industrial and precision applications. Unlike pure metallic elements, tungsten carbide gains its characteristic rigidity from a necessary co-sintering process involving a metallic binder, most commonly cobalt (Co)/) or nickel (Ni)/),…

3. Tungsten Carbide

   Linked via "cobalt (Co)"

   The primary method for producing technical-grade tungsten carbide involves the carburization of tungsten oxide ($\text{WO}3$)/) or pure tungsten metal powder, followed by hot isostatic pressing (HIP) or liquid-phase sintering with a binder metal [2]. The stoichiometric ratio of tungsten to carbon is precisely controlled, as deviations from $\text{WC}$ result in undesirable phases such as tungsten sesquicarbide ($\text{W}2\text{C}$)/), which significantly compromises th…
