Standing Hammer

-

Hammer constant - proportional coefficient in expressions determining the dependence of the influence of the distance between objects of different chemical compositions (particles, particles, eg colloidal, macroscopic objects - distinct phases) and various shapes. The size of the Hamaker's constant also depends on the medium in which these objects are located - for example, it allows for easy explanation of attraction and repulsion between physical bodies depending on the nature of the medium in which they are immersed.

The value of the Hammer A constant for Van der Waals interactions defines the equation: A = π 2 × C × ρ 1 × ρ 2 {\displaystyle A=\pi ^{2}\times C\times \rho _{1}\times \rho _{2}}

where ρ 1 {\displaystyle \rho _{1}} i ρ 2 {\displaystyle \rho _{2}} is the number of atoms in a unit of volume of interacting bodies, and C is a factor for the potential of atomic-atom pairs.
