The mineral component of bone, primarily hydroxyapatite, contributes to its hardness. Hydroxyapatite is a crystalline form of calcium and phosphate that provides strength and rigidity to bone tissue. The arrangement of collagen fibers in the bone matrix also plays a role in its hardness.
What else can I help you with?
What material in bone is responsible for giving it hardness?
red bone marrow and calcium
How to identify a hardness of a unidentified material?
To identify the hardness of an unidentified material, you can use a hardness test such as the Mohs scale, Vickers hardness test, or Rockwell hardness test. These tests involve applying a specific amount of force to the material's surface and measuring the indentation or scratch it creates to determine its hardness.
What is hacksaw hardness testing?
Hacksaw hardness testing is a simple and rudimentary method used to estimate the hardness of a material. It involves cutting a groove into the material with a hacksaw blade and then comparing the resistance encountered while cutting to a known material hardness scale. This method is not as precise as standard hardness testing methods but can provide a rough estimate of the material's hardness.
Which physical property is shown by scratching one material with another?
The physical property shown by scratching one material with another is hardness. Hardness is a measure of how resistant a material is to scratching or indentation.
Hardness of a material that scratches the knife blade?
The hardness of a material that scratches a knife blade would typically be higher than the hardness of the knife blade itself. This implies that the material is able to physically deform or remove material from the knife blade due to its greater hardness. This property is commonly assessed using the Mohs scale of mineral hardness.
What material in bone is responsible for giving it hardness?
red bone marrow and calcium
If a material has a hardness of 8 can it not be scratched by a material with a hardness of 7?
Yes, a material with a hardness of 8 can scratch a material with a hardness of 7, but not the other way around. Hardness is a measure of a material's resistance to scratching, so a material with a higher hardness value can scratch a material with a lower hardness value.
What are the factors on which hardness of a material depends?
Hardness of a material depends on the type of bonding between atoms.
How to identify a hardness of a unidentified material?

Hardness of a material that scratches the knife blade?
The hardness of a material that scratches a knife blade would typically be higher than the hardness of the knife blade itself. This implies that the material is able to physically deform or remove material from the knife blade due to its greater hardness. This property is commonly assessed using the Mohs scale of mineral hardness.
Why hardness is a intensive?
Because the hardness is not dependent to the size of a material sample.
What is the Brinell hardness test used for?
The Brinell hardness test is a standardized test in material science. It measures the hardness of a metal by measuring the indentation on the material caused by an indenter.
What is the property of the material by which it offers resistance to scratching or indentation is?
The property of a material that offers resistance to scratching or indentation is called hardness. Hardness is a measure of a material's ability to withstand surface deformation under applied force, such as scratching or denting. It is an important characteristic in materials science and engineering for determining a material's durability and suitability for specific applications.
What is the hardness of EN 18 material?
EN 18 material has a hardness range of approximately 58-64 HRC (Rockwell Hardness). This makes it a relatively hard material suitable for applications requiring good wear resistance and strength.
The hardness of bone is due to what?
The hardness of bone is due to the calcium salts deposited in it.The exceptional hardness of bone, which allows it to resist compression, is attributed to the presence of inorganic hydroxyapatites. Hydroxyapatites such as calcium phosphates are particularly important for bone hardness. Organic substances such as collagen fibers contribute to tensile strength, but not to hardness.the presence of inorganic hydroxyapatites.
