Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention prevents personal injury due to conventional glass breakage, and enables the use of glass in various industries such as solar power generation and heat exchange air conditioning using high-strength glass tiles due to increased tensile strength. Opening up new fields.

[Prior art j] Current glass is manufactured using an ancient manufacturing method, but no essential improvements have been made, such as strengthening strain stress through rapid cooling, strengthening shrinkage through immersion, and preventing scattering through bonding.

[Problems to be solved by the invention] Conventional glass hardly elongates under low stress, but when stress exceeds a certain level, it suddenly begins to elongate and breaks instantly. CaCN,
By adding , the critical value of the stress intensity factor increases and the tensile strength increases, making it difficult for fracture to occur.

Means for Solving Problem E] This manufacturing method is a kind of hybrid device that brings out the excellent properties of each by combining the long-range order of ceramic and the short-range period of amorphous.

From the perspective of the diffusion coefficient of solid-state ionics, visible light means that the light energy in the visible light range cannot excite the electrons in the glass. It returns to an ion and undergoes an electronic transition to become a neutral atom.

The electronic state of a molecule is not determined by the equilibrium position of the atomic nucleus, especially the equilibrium position of the ground state, but moves near the equilibrium point, resulting in vibronic interactions that break the symmetry.

Excitation is a phenomenon in which vibrations and rotations between nuclei, not valence electrons, change the electric dipole moment, and resonance absorbs external electromagnetic waves.In glass, the vibration between 5i-0 causes Si to +, O
has a - charge and creates a dipole moment. The degree of freedom of vibration is an element in calculating the kinetic energy of the nucleus,
It is correlated with the potential energy between the electron and the nucleus. The excited state has a different electronic structure than the ground state and is an electronic isomer.

Generally, the energy is in the middle of the band gap, and since E9 is large in oxides, it is rarely mixed with the S and P bands, and forms a localized level or a narrow d band within the crystal.

As the atomic number increases, the d-band becomes more stable relative to the lower valence band, lowering its unit. Therefore, even if the structure is the same, it will have various properties depending on the number of dN atoms and how the energy bands are mixed.

Mechanical and electrical strain caused by the formation of a space lattice and gain in intracrystalline d-electron energy are factors for stability. That point C,N
The valence electrons only partially fill the P orbitals, so the wave function does not have spherical symmetry around each atom.

The energy of a crystal structure depends sensitively on the arrangement of adjacent atoms, and interactions cannot be said to be central. On the other hand, the valence electrons of elements with large atomic numbers are in an energy region where many different electronic states exist, and become a complex state where the directionality is averaged out and lost.

3i is hard, stable and has a diamond structure, and S
It completely fills the p7 binding band and an anti-binding band is formed. Electrons are distributed in the direction of neighboring atoms in tetrahedral coordination, with 4 electrons per atom filling the bonding band, and the energy gap is large. Using reversible phase transition, we define one unit of bandtail energy, and define various optical band gaps and optical property constants that suppress light diffusion.

Next, from the perspective of the crystal growth mechanism in structural chemistry, we fix all orientations and consider the relationship with the school of fish coordinating with them, and consider the correspondence between physical properties such as natural polarization and optical rotation, and the structure. For example, the symmetry elements (symmetry axis, rotation axis, rotation axis, translation axis, and helical axis) with respect to the principal axis of the spatial lattice are taken into account to approximate an optically isotropic body.

N in Group 5 is a unique entity, and the others have a triangular pyramidal bond angle e
oLC - Although small and distorted and once unstable at room temperature, only N is a diatomic molecule and corresponds to a network structure of hexagonal plates made of regular triangular plates arranged vertically and parallelly, and has small metallic properties and a dumbbell-shaped molecule. are arranged in a hexagonal close-packed pattern. Also, C in group 4
has various transformations with symmetry of 60,000 crystals in three-dimensional space.

This tetrahedron, in combination with a face-centered cubic lattice (close-packed structure) of Ca, fills half of the tetrahedral gap, approaches a perfect image crystal group, and scatters less light. bI>a of PBC vector
> We performed approximate calculations of the growth theory, Hartmann's emission, and adhesion energy, and determined the structural factors such as the interplanar spacing and diffraction intensity of the atomic scattering factors, and eliminated the diagonal crystals and A normal crystal lattice structure is formed in which the symmetry axis coincides with the crystal axis.

The strain and rIl friction caused by the deformation of the 5iOz ring near the transition point in the delayed elasticity effect result in irreversible viscosity relaxation, which is incorporated into the processing conditions.

The increase in melting point due to increase in coordination number is higher than the ionic radius, and the diagram of dielectric constant → scattering due to atomic arrangement can be solved by using induction and resonance effects.

The particle size is aimed at maximizing the use of surface energy, and as this has the greatest effect on the growth of abnormal particles during diffusion transition, air bubbles, devitrification, and a decrease in tensile strength, the particle size is subdivided and homogenized.

By bringing the refractive index of the grain layer and grain boundary layer closer together, and paying attention to the growth of abnormal grains due to fluctuations in chemical composition and lattice constant, we prevent devitrification.

[Effect of the invention] By adding Ca CN, microcrystals are generated, and the layered network structure of conventional glass is sterically cross-linked to a three-dimensional network structure.
The tensile strength increases dramatically and absorption and scattering of visible light can also be prevented.

It also means conservation and saving of energy resources according to the law of entropy.
