At low volume fractions the specimens have a dispersed fracture pattern with a large amount of secondary cracking. That is, fracture occurring at sites located far from the main crack tip. There is less secondary cracking as the volume fraction of gold increases and fracture becomes more concentrated around the crack tip.
Fracture is jagged. Streak is golden yellow. Hardness is 2.5 – 3.

Why is gold more resistant to fracture than other materials
Because more polymer must be present at lower volume fractions, this bridging becomes very common, resulting in increased fracture resistance. This mechanism is also explained by the increased fracture resistance of metal-impregnated ceramic rods [65], [69].
What is fracture
A “fracture” is the breakdown of a metal, exposing a useful, uneven surface: the topography of a heavily cracked surface is an important feature closely related to crystal growth, and in some cases can indicate the health of the metal. .
What are the most common fragility fractures
In this definition of brittle fractures, fractures of the hip, spine, and forearm are most common.
What factors affect the recovery of gold
This fact affects the yield of gold, as compressed gold particles have a better smaller surface area and can react more efficiently with the reservoir, and the trading action is very slow compared to small nuggets or spherical particles.
What are tiny pieces of gold called
Its rarity and physical properties make it one of the most valuable natural resources on the planet. Gold, if it is often found in rocks, is always practically pure. Large pieces of gold are called blocks, and small pieces are called gold dust.
What are the physical properties of gold
Gold is a conductor of heat and electricity.
Gold is simply stretchable: it can be stretched to the thinnest thread.
Gold has a high coefficient of thermal reflection of light.
Gold is valued for the beauty of the nation.
Gold is malleable, so it can be flattened into extremely thin sheets.
