At Chelyabinsk State University (ChelSU), an innovative method for synthesizing material for mass production in the field of optics and electronics has been developed and patented. It makes it possible to reduce the production time of material batches by almost half.
The method is based on the use of modified sulfonated polystyrene as a precipitant. The material is created from readily available raw material — foam plastic. Combined with the optimization of temperature-time parameters (calcination at temperatures from 950 to 1,050 degrees for 2.5-3 hours), the solution delivered a technological breakthrough, the scientists emphasized.
This concerns the synthesis of yttrium aluminum garnet, which is used in the production of infrared lasers employed for laser hair removal, as well as in the creation of white LEDs and lasers. The new method makes it possible to reduce the material synthesis time by 53% compared with existing counterparts.
The patented method accelerates the production process by reducing the number and duration of individual technological operations. The final calcination temperature has been lowered, which also leads to energy savings.
