Abstract

Abstract A process for producing structures from synthetic single-­crystal pieces having identical major component and crystal systems by chemically bonding to produce integration and simulation. From a physical viewpoint, synthetic single- crystal pieces can endure high and low temperatures, and rapid heating and cooling as they have,high melting points. Their hardness is considerably higher than non-crystals. From a chemical viewpoint, synthetic single-crystal structures provide superior chemical resistance and are free of corrosion and quite stable chemically. Structures produced from synthetic single-crystals provide features superior to non-cyrstals but are not as advantageous because they are so hard that they are not easily dissolved and processing them is difficult. The greatest difficulty with synthetic single-crystals is that unlike non-­crystals they cannot be melted together. The process of the present invention makes structures of synthetic single-crystals that are placed together like non-crystals. Therefore, with the process of the present invention, new synthetic single-crystal structures of larger or smaller complicated precise shapes having applications in optical, chemical, and physical fields may be produced. The structures from synthetic single-crystal pieces are comprised of a plurality of colorless synthetic single-­crystals or colored synthetic single-crystals having the came prime component and either no color or color impurities contained therein. The synthetic single-crystal pieces are optically polished on both parallel ends which intersect at a particular crystal axes with a particular angle and the polished opitcal end faces are optically bonded with identical axes, identical axial angle, and identical axial ratio. The single-crystal pieces are all uniformally heated to chemically combine them to integrate them together.
