What are crystallographically equivalent planes?
i. Any set of parallel and equally spaced planes that may be supposed to pass through the centers of atoms in crystals.
How do you find equivalent crystallographic directions?
60 second clip suggested5:00Direction Indices and Equivalent Directions in a Lattice – YouTubeYouTubeStart of suggested clipEnd of suggested clipOk so along x axis you have 1 units along Y axis you have 1 units along Z you have 0 units ok. SoMoreOk so along x axis you have 1 units along Y axis you have 1 units along Z you have 0 units ok. So you have resolved this vector which represents this direction along XY. And z axes.
What is crystallography direction?
i. Refers to directions in the various crystal systems that correspond with the growth of the mineral and often with the direction of one of the faces of the original crystal itself. ii. Vectors referred to as crystallographic axes.
What is equivalent direction?
The specific symmetry of a crystal system defines (hkl) planes and [uvw] directions which are identical to each other. As an example, specific relations for a cubic system are given: <100> = [100], [010], [001], [-100], [0-10], [00-1]
What is the difference between lattice and crystal?
What is the difference between Lattice and Crystal? Lattice describes the structure of crystals. When a group of molecules tends to arrange each unit repeatedly at a lattice point, a crystal is made. In a crystal structure, there is a pattern of arranging the atoms or units.
What is family of crystal directions?
Crystallographic directions (continue) • denote the direction by [uvw] • family direction , defined by transformation. • material properties along any direction in a family are the. same, e.g. [100],[010],[001] in simple cubic are same.
Is crystal lattice and space lattice same?
Crystal lattices The three-dimensional network of imaginary lines connecting atoms is called the space lattice. A crystal is an arrangement in three dimensions of atoms or molecules in repetitive patterns.
What is lattice point in physics?
A Lattice point is the position in the unit cell or in a crystal where the probability of finding an atom or an ion is the highest. In other words, the atoms or ions occupy the lattice points in a crystalline solid.
