Empirical evidence for the fractionation of carbon

The magnitudes of isotopic fractionation during diamond formation in the mantle buffered around QFM at 1200°C are +1‰ for diamond‐CH 4 [Bottinga , 1969; Thomassot et al ., 2007] and −3.5‰ for diamond‐CO 2 [Richet et al ., 1977].When the f O 2 is buffered below the IW buffer, much larger Δ 13 C values have been observed (where Δ 13 C = (1000)*lnα ≈ δ 13 C phase 2 − δ 13 C

boron carbide zirnia - domazzi.cz

Boron Carbide, or B4C, is an extremely hard ceramic material discovered in 1899. With a Mohs hardness between 9 and 10, boron carbide is one of the hardest synthetic substances known, being exceeded only by cubic boron nitride (cBN) and diamond. Besides, it has good chemical inertness and high neutron absorption cross section.

Moissanite: Stone / Crystal Meaning, Healing …

Properties - Moissanite is formerly referred to as extraordinary marble revealed by Henri Moissan having a chemical formula SiC and diverse crystalline polymorphs. Earlier this marble had been synthesized into a complex know as Silicon carbide (SiC). This stone''s formation is held by the covalent bonding akin to that of diamond, this allows moissanite to withstand high pressure up to 52.1
