Saphire products
Thanks to its unique properties, sapphire is used in all industries that require materials characterized by a high hardness (9 in Mohs scale) and strength, a unique crystallographic structure, special chemical and physical properties, as well as permeability of visible and invisible light. Among the numerous areas of application of sapphire, one can find the following:
2 inch Ingot Specification4 inch Ingot Specification6 inch Ingot Specification
Alumina fedstock
Knowledge, efficient equipment and human skills are extremely important, however, the essential component for the production of high quality sapphire material is the highest quality raw material – Al2O3.

In cooperation with the POLYCOR company, Juropol created a highly efficient technological process of production of pure aluminium oxide, which serves as the base material for producing sapphire crystals. What makes us special is the unique, patented powder refinement technology that allows eliminating any impurities left after the raw material production process.

The 99.999%-pure aluminium oxide that we offer may be supplied as a granulated product or in the form of a block matching the shape of crucible used to produce crystals, which allows optimizing the furnace charge, considerably reduces the duration of this operation, and what is extremely important, reduces the possibility of penetration of impurities that usually, with a conventional charge, enter the furnace during breaking up or laying little pieces of raw material in the furnace.

Constant control of quality of the material on all stages of production is realized using analytical devices. This, along with fabrication of the final product, which is a high quality crystal, makes for the most reliable confirmation of raw material quality.

Company profile
Juropol Sp. z o. o. is a family business founded in 1995. Initially, the firm produced and processed high quality quartz glass. In 2001, it extended its activity to the supply of raw materials for glass production and metallurgy. The decision to launch sapphire crystal production and enter an entirely new market was a turning point. The year 2007 marked the beginning of its way to emerging among global sapphire suppliers. Motivation and enthusiasm of our team and its constant pursuit of improving processes and product quality came to be a solid foundation for establishing a position of a reliable supplier of high quality crystals. Sapphire became an inspiration for further work. Based on observations, insightful research and professional experience, the development-oriented team of Juropol took a step further and designed its own furnace for growing sapphire crystals using the Kyropoulos method. In 2010, these furnaces complemented our offer along with training courses for future users. In the same year, a market niche has been filled by founding POLYCOR Sp. z o. o., a subsidiary company producing raw material used for sapphire crystal growth. POLYCOR‘s unique raw material refinement technology and self-developed production line allow manufacturing an optimal, tailored raw material.

Our constant research and innovation-oriented approach make us a strong supplier – a supplier worth cooperating with to create entirely new, complex solutions.

For the present, we offer our Customers:

sapphire ingots up to 6“ in diameter;
furnaces for growing sapphire crystals using the Kyropoulos method
