Why FCC crystal structure has more slip plans thenHCP?
FCC crystal structure has 12 slip planes because of its cubic symmetry, which allows slip to occur in many directions. HCP crystal structure, on the other hand, has 3 slip planes due to its hexagonal close-packed arrangement, which restricts the slip to fewer directions.
What is structure of zinc crystal?
It is a box shape. Here is some more info on the subject matter pertaining to your specific circumstances:Space group: P63/mmc (Space group number: 194)Structure: hcp (hexagonal close-packed)Cell parameters: a: 266.49 pm
How do you calculate APF of HCP?
The atomic packing factor (APF) of a hexagonal close-packed (HCP) structure is calculated by taking the volume of atoms in a unit cell divided by the total volume of the unit cell. For HCP, the APF can be determined using the formula: APF = (3 * sqrt(3) * (0.25)) / (2 * sqrt(2)) This simplifies to APF = 0.74
From SAED pattern from TEM how you determined which element is present?
you have to measure the distance and angles between the main point and the surrounding pattern from the diffraction you create. Each crystal has its own structure (BCC, FCC, HCP, etc...) and each element in the crystal structure determines the lattice spacing....
What are the allotropes of platinum?
Platinum does not seem to have discovered allotropes; instead it has isotopes which are the nearest thing from what I could discover online. Not only that but platinum is so rare no one really has enough money to test it enough to discover whether it does have allotropes are not.

How do you calculate the volume of a HCP crystal?
Are you takling Material Science class? Volume of HCP crystal = (a^2) (c) cos30 Im taking Material Science and Engineering
What is the lattice parameter of a hexagonal close-packed (hcp) crystal structure?
The lattice parameter of a hexagonal close-packed (hcp) crystal structure is the distance between the centers of two adjacent atoms in the crystal lattice. It is typically denoted as "a" and is equal to 2 times the radius of the atoms in the structure.
How do you open program compatibility wizard?

What is the difference between hcp and ccp closed packing?
HCP (hexagonal close-packed) and CCP (cubic close-packed) are both types of close-packed crystal structures. The main difference lies in the arrangement of atoms - HCP has two alternating layers of atoms, while CCP has three alternating layers. HCP has a hexagonal unit cell, while CCP has a cubic unit cell.
What is the coordination number in hcp?
The coordination number in hexagonal close-packed (hcp) structures is 12. This means that each atom in an hcp lattice is in contact with 12 surrounding atoms.
What is the crystal shape of aluminum oxide?
Aluminum oxide typically forms in a crystal shape known as hexagonal close-packed (hcp) structure. This structure consists of closely-packed layers of aluminum and oxygen atoms arranged in a hexagonal pattern.
Volume of a HCP unit cell?
The volume of HCP is 8*pi*r^3 or 25.13*r^3

Number of atoms in hcp unit cell?
"There are 6 atoms in the hcp unit cell. The hex shape has six atoms at the points that are direct translations of each other making 1 atom for the top hex and one atom for the bottom hex. That's 2. The atom in the center of the top and center of the bottom are translations giving 1 more. That's 3. Then there are 3 atoms in the middle region of each cell bringing the total to 6." The answer should depend on how you choose your unit cell. In the primitive hexagonal cell we have 1 atom at each of the corners of the cell (each is "worth" 1/8) and 1 atom within the cell giving us 2 atoms/unit cell. (Note: the 'primitive hexagonal cell' above actually refers to the parallelpiped structure that the hexagonal unit cell consists of: the hexagonal 'unit' -it cannot technically be referred to as a unit cell, because unit cells are the most reduced form of the crystal structure- can be divided into 3 parallelepipeds.)
