Growth of Mg–Al Spinel Microcrystals on a Sapphire Surface Using A Solution-Precipitation Method

A solution-precipitation process was used to grow Mg–Al spinel microcrystals at etched pits in a c-axial sapphire single crystal surface. In the proposed innovative growth process, the etched pits function as heterogeneous nucleation points. The quenching and aging treatment causes Mg ions to diffuse into the sapphire crystal, precipitating as microcrystals at the etched pits. We found the precipitated crystals to be Mg–Al spinels with a triangular pyramidal shape.

The optically pumped solid-state laser active element is the most widely used inorganic oxide crystals. This oxide material either garnet or corundum structure is made is called Czochralski crystal growth technique pulling industrial scale preparation. Czochralski growth in the country's most advanced along with the participation of a large size, the key variable is the growth of high-quality oxide crystals is described in this description. Ruby, yttrium aluminum garnet, sapphire crystal growth and description presented in titanium. Composition under ambient atmosphere, the variable crystal growth, crystal type and the impact of individual environmental conditions to be described. Suitability for different oxide Czochralski crystal growth process, the focus is on materials properties, e.g., the phase diagram means (melting consistency), the melting temperature of the crucible material, dopant ions impact, and high temperature melting Body Chemistry discussion.
