SapphiT®  - Tempered Sapphire

Sapphire – Al2O3 single crystal - has outstanding physicochemical properties: extraordinary mechanical resistance, high hardness and shape stability even at temperatures approaching 2000°C, excellent optical properties, high thermal conductivity, low electric conductivity, no porosity, strength even in extreme temperature conditions, outstanding chemical resistance even to fluorination agents and perfect crystal lattice. All of this makes sapphire a much sought-after material in industry and science.
Crytur is a company with one of the longest traditions in single crystal manufacturing, which was founded in 1935 as the “Research Group for Gem Analysis”.We have been producing sapphire single crystals, rods, ribbons, tubes and fibres since 1978. Our more than 30 years of expertise and research background have resulted in optimised patented technology for the manufacture of SapphiT® – Tempered Sapphire, an unmatched material with a perfect lattice structure resulting in minimum crystal tension and excellent physical and chemical purity higher than 5N. Crytur is the only EU manufacturer of EFG sapphire (not a re-seller). As such, we can offer the required combination of high quality, short delivery times, custom-made solutions and competitive prices which do not find a real match anywhere else in Europe.
