Why Diamond Is So Hard and Stable
How the carbon lattice and tetrahedral bonding give diamond its hardness, thermal conductivity, chemical resistance and optical clarity, and where its limits lie.
Carbon And Hard Materials
Diamond Properties
Why diamond behaves the way it does, from bonding to impurities.
Chemical Inertness and the Limits of Oxidation
Where diamond resists acids, bases and solvents, and the temperatures at which oxidation and graphitization begin to degrade it in air or inert atmospheres.
Cleavage Planes and Brittleness in Diamond
Why diamond, the hardest common material, can still chip or split: how cleavage planes, brittle fracture and flaws limit toughness, and how grain structure helps.
Diamond Hardness Explained Without the Jargon
What hardness actually measures, how scratch and indentation scales differ, and why diamond comes out on top of every common scale without being unbreakable.
Electrical Behavior and Boron Doping in Diamond
How pure diamond insulates, how small amounts of boron or other elements make it conduct, and why doping diamond is harder than doping silicon.
How Transparent Is Diamond Across the Spectrum
How diamond transmits light from the ultraviolet through the infrared, what absorption bands exist, and how impurities, grain boundaries and surfaces limit clarity.
Nitrogen and Other Impurities in Diamond
How nitrogen, boron and structural defects change diamond color, electrical behavior and optical or thermal performance, and how diamond types are classified.
Single Crystal and Polycrystalline Diamond Compared
How a single crystal differs from polycrystalline diamond in strength, wear behavior, size, optical and thermal quality, and cost, and where each is typically used.
Why Diamond Conducts Heat So Well
How lattice vibrations, or phonons, carry heat through a pure diamond crystal, why light, tightly bonded atoms matter, and what reduces conductivity in real material.
