Physical Properties of Amalgam. The most important physical properties of amalgam are flow and creep, dimensional change, and strength.
(1) Flow and creep. Flow and creep are characteristics that deal with an
amalgam undergoing deformation when stressed. The lower the creep value of an
amalgam, the better the marginal integrity of the restoration. Alloys with high copper
content usually have lower creep values than the conventional silver-tin alloys.
(2) Dimensional change. An amalgam can expand or contract depending
upon its usage. Dimensional change can be minimized by proper usage of alloy and
mercury.
(3) Compression strength. Sufficient strength to resist fracture is an
important requiand the degree of porosity in the amalgam restoration.
rement for any restorative material. At 50 percent mercury content, the
compression strength is approximately 52,000 pounds per square inch (psi). In
comparison, the compressive strength of dentin and enamel is 30,000 psi and 100,000
psi, respectively. The strength of an amalgam is determined primarily by the
composition of the alloy, the amount of residual mercury remaining after condensation,

Amalgam is typically made up of Mercury, silver, tin, and copper. These components are mixed together to form a strong and durable dental filling material. The mercury acts as a binder, while the other metals provide strength and stability.
1-Alloys contain atoms of different sizes, which distorts the regular arrangements of atoms. This makes it more difficult for the layers to slide over each other, so alloys are harder than the pure metal.
It is more difficult for layers of atoms to slide over each other in alloys
It is possible that I'm misreading this article, but if I am not, it appears there are several. Compressive strength, tensile strength, transverse strength, and trasnverse deflection as well as flow. Others seem to include dynamic creep, static creep, and slow compressive strength.
Amalgam is commonly referred to as an alloy of mercury and other metals. In dentistry, mercury is blended with silver, copper, indium, and zinc to form common amalgam fillings. Another example is gold amalgam, which is formed when the metallic gold is extracted from the ore using liquid mercury. Yet another amalgam is used when chlorine is electrolytically produced from sodium chloride, where sodium amalgam is built instead of hydrogen. In a broader sense, any mixture of two or more components, not only chemicals, that will or have become inseparable are called "amalgam".
the properties of alloys depends upon the alloy you are talking about. But their properties completely differ from their constituent metals. For example, when soft iron is mixed with carbon(0.05 %), it forms stell which is hard and does not rust easily. or when soft iron is mixed with nickel and chromium, it forms stainless steel which is hard,strong n does not rust at all.all these properties of steel n stainless steel r completely different from that of iron.

What are the solute of dental amalgam?
The main solutes in dental amalgam are silver, tin, and copper. These metals are mixed with mercury to form a stable alloy used in dental fillings.
Amalgam in a sentence?
An amalgam is a mixture or blend of different elements or substances, such as a dental amalgam used in fillings.
Is amalgam a homogeneous?
Yes, amalgams are homogeneous.Amalgam [note correct spelling] is usually a homogenous mixture. An amalgam is a solid alloy of mercury, the only metal element that is liquid at standard temperature and pressure, with some other metal.
What is an amalgam restoration?
An amalgam restoration is a filling made of a combination of metals, including silver, tin, copper, and mercury. It is a durable and long-lasting material commonly used to fill cavities in teeth. The mercury in the amalgam is mixed with the other metals to form a safe and stable compound.
Sodium amalgam reaction?
Sodium amalgam is produced by dissolving sodium metal in mercury. This amalgam can be used in organic synthesis reactions as a reducing agent. When sodium amalgam reacts with water, it produces hydrogen gas and sodium hydroxide.
Is silver the main component of amalgam?
"Amalgam" means a solution with mercury metal as the solvent and another metal (pretty much anything but iron, which won't amalgamate) as the solute. So...mercury is the main component of amalgam.
What is the process that separates the components of amalgam?

Is amalgam tattoo chemically unstable?
no ....... amalgam tatoo is not chemically unstable . silver amalgam is dental restoration in which there are 2 major components . 1st :- silver alloy which contains silver , cupper , zinc . 2nd :- mercury . these 2 components have to be mixed togather to make a workable mix . amalgam tattoo is caused by leaching of mercury from the restoration . though mercury is harmful for th body , but the amount of mercury is negligeable to cause any reaction . so dont worry . dr. naman rana
What are the solute of dental amalgam?
The main solutes in dental amalgam are silver, tin, and copper. These metals are mixed with mercury to form a stable alloy used in dental fillings.
What are the components of amalgam?
Amalgam typically consists of silver, tin, copper, and mercury. Silver provides strength and durability, tin helps with workability, copper assists with corrosion resistance, and mercury acts as the binding agent to hold the mixture together.
How can you separate amalgam?
Amalgam can be separated by using a process called distillation, where the components are heated to their boiling points, causing them to vaporize at different temperatures and then recondense back into separate phases. Another method is to use chemical means such as adding a reactive substance to selectively extract one component of the amalgam.
Is amalgam or composite stronger?
