Main components of amalgam

Answer 1

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,

Answer 2

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.

Answer 3

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

Answer 4

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.

Answer 5

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".

Answer 6

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.
