Tantalum carbides (TaC) form a family of binary chemical compounds of tantalum and carbon with the empirical formula TaC x, where x usually varies between 0.4 and 1. They are extremely hard , brittle, refractory ceramic materials with metallic electrical conductivity .

Theoretically predicted phase diagram of carbon. The equilibrium pressure and temperature conditions for a transition between graphite and diamond is well established theoretically and experimentally. The pressure changes linearly between 1.7 GPa at 0 K and 12 GPa at 5000 K (the diamond/graphite/liquid triple point).
The phase diagram shows, in pressure–temperature space, the lines of equilibrium or phase boundaries between the three phases of solid, liquid, and gas. The curves on the phase diagram show the points where the free energy (and other derived properties) becomes non-analytic: their derivatives with respect to the coordinates (temperature and ...

Pobedit (Russian: победи́т) is a sintered carbide alloy of about 90% tungsten carbide as a hard phase, and about 10% cobalt (Co) as a binder phase, with a small amount of additional carbon. Developed in the Soviet Union in 1929, it is described as a material from which cutting tools are made.
Diamond and graphite, two different allotropes of carbon. Carbon is the chemical element with atomic number 6, occurring as 12 C, 13 C and 14 C. [25] At standard temperature and pressure, carbon is a solid, occurring in many different allotropes, the most common of which are graphite, diamond, the fullerenes and amorphous carbon. [25]
