What Is Ductility in Chemistry?
What Is Ductility in Chemistry?What is ductility in chemistry? Is it really? Ductility in chemistry has nothing to do with the hardness of a material, but is rather a measurement of its resistance to liquid or vapor.Ductility in chemistry can be defined as the toughness of a material. It is a measure of how resistant a material is to other liquids and gasses, such as carbon dioxide, steam, air, moisture, alcohol, and solvents.Ductility in chemistry is measured by the following formula: the ductility factor (DF) is the ratio of the ductility (the speed at which fluids will flow) of a material to the square of the molecular weight of the material. If the DF is less than 1, the material is not .For example, imagine you are heating some material. You pour some oil into the container and heat it up. The material heats up very quickly. Now if you were to measure the temperature of the oil with a thermometer and it reads 250 degrees Celsius, you can see that the material is ductile and that it can take a large volume of oil to raise the temperature of the material.Now if you were to add more oil to the container, you would find that the oil would begin to penetrate the material. This would mean that the oil would be able to flow out and would create an area where the gas would be held.This is the major problem with this type of testing. The properties of the material are not evaluated, and thus the grade can be moved up or down without knowledge of the material's molecular density. An average grade will sometimes be assigned to materials with little or no structural or ductility in nature.Materials such as glass, plastic, rubber, and paper are considered ductile. Many times materials such as marble, granite, and tile are not in nature and therefore have to be tested using non-ductile criteria. This can result in unacceptable grades being assigned to a material.This can happen even if the grade of the material is not necessarily wrong. It may be that the material is du ctile enough that it can be ductile in a laboratory setting but not actually ductile in the real world.
