There is also an intermolecular force between the crystals and molecules of light burned magnesium powder, which is called intermolecular force. The intermolecular force is related to the polarity of molecules, and the molecules are electrically neutral in general. Because the positive charge of a molecule is equal to that of a negative charge. However, in terms of the distribution of these two charges within the molecule, molecules can be divided into polar and non-polar molecules.

Each kind of charge has a "charge center". If the relative positions of the positive and negative charge centers are expressed by "+" and "one", the molecules with overlapping positive and negative charge centers are called non-polar molecules, and the molecules without overlapping are called polar molecules. The center of the positive and negative charges in the molecule carries q, the distance is l, and the product of the two is called the dipole distance p--P.

The formation of the strength of lightly fired magnesia spheres The structural strength of lightly fired magnesia spheres mainly depends on the effect of the internal structural force. Theoretically, the formation process of light burned magnesia ball is mainly the two processes of physics and chemistry. The light burned magnesia ball in physical process is extruded by mixing light burned magnesia powder with water. The diameter of light burned magnesia powder is about 0.074mm, and has a molecular or crystal structure in physics.

According to a large number of experimental and theoretical research results, there is an interaction between charges, the same charges repel each other, and the different charges attract each other. It is shown that there is an interaction force between two point charges, whose magnitude is proportional to the product of the electric quantity of the two point charges and inversely proportional to the square of the distance between the two point charges. The unit crystals of light burned magnesia also have equal positive and negative charges.

There is always a dipole in a moment. This kind of dipole is called an instantaneous dipole. The intermolecular force is related to the polarity of molecules, and the molecules are electrically neutral in general. Because the positive charge of a molecule is equal to that of a negative charge.
