Alfa Chemistry Expands Its Production Lines by Adding Single Crystal Products

On July 20, 2018, due to the increasing demands from the customers around the world, Alfa Chemistry announced the launch of single crystal products to expand its production lines.

Single crystals are materials in which the entire sample has a continuous and unbroken lattice at the edge of the sample, without grain boundaries. The particles inside the single crystal are regularly and periodically arranged in the three-dimensional space, or in other words, the whole crystal is composed of the same space lattice in the three-dimensional direction. Single crystals have unique properties including mechanical, optical and electrical properties. Single crystal material is a new material that is increasingly used. In addition to their value in certain gemstones, they can also be used industrially in technical applications, especially in the fields of optics, electronics and semiconductor.

Among the single crystal materials, pure element single crystals play an important role in the field of advanced materials. In general, Single crystals include pure elements, alloys, compounds and oxides. And the metals are generally considered to be pure elements. Pure element single crystals include Si, non-ferrous metals (Cu, Zn, Co, Cr, Ni), rare metals (Ru, Ta, Nb, In, Ge, V), precious metals (Au, Ag, Pt, Pd) and transition metals (Fe). Si, Ge single crystals are commonly used in semiconductors. Bi, Cu, Ge, Ni single crystal are generally used to prepare monochromators.

The single crystal substrate material refers to a single crystal wafer for epitaxial growth of a crystal thin film. With the continuous development of the optoelectronics industry, the performance and quality requirements of the film are getting higher and higher, and the original substrate material has been unable to meet the requirements, so various single crystal materials are used as the substrate. Nowadays, the single crystal substrate materials have become the basis of the optoelectronics industry. SiNx films have been widely used in microelectronics and micromechanical systems because of their high hardness, high temperature resistance, good thermal conductivity, insulation and excellent photoelectric properties. GaN single-crystal thin film grown by epitaxial growth on a sapphire (mainly Al2O3) substrate is the most preferred material for preparing high temperature, high frequency, and high power devices. Barium titanate (SrTiO3 ) is a commonly used electronic functional ceramic material with high dielectric constant, low dielectric loss and good thermal stability.

“The single crystal materials have a wide range of applications in optics and electronics due to their unique physical and chemical properties including electrical, optical, thermal and mechanical properties.” Said Dr. Brenda Randy, the marketing manager of Alfa Chemistry. “So we decide to expand our production lines by adding Single Crystal products to satisfy the needs of our customers .”
