Product Details
SrF2-Crytal
►Description
Strontium Fluoride (SrF2) is one of the most important
alkaline-earth fluorides. It has many physical properties, such as
low energy phonon, high ionization, high resistance coefficient and
good anion conductivity. It has been widely used in light-emitting
devices, optical imaging, biomarkers, anion conductors and other
fields. Compared with oxide and calcium fluoride, strontium
fluoride has lower phonon energy, higher thermal conductivity and
negative thermal optical coefficient, especially negative thermal
optical coefficient, which can compensate the thermal lens effect
in the process of laser oscillation. Strontium fluoride has
promoted the research of optical materials and the improvement of
optical instruments with its unique material structure and
properties
►Features
- Poorly soluble in water, ethanol and methanol
- High conductivity and optical properties similar to calcium
fluoride
- Can transmit ultraviolet and infrared waves
- Very dangerous to the health, poisonous when inhaled or ingested
and in low concentration can cause irritation to skin and eyes.
- Not flammable
►Application
- UV and VUV spectroscopy
- Manufacture optical materials for different devices, like glasses,
windows and lenses
- Intermediate infrared laser matrix material

——growing crystals, linking values
We are seller of crystals. At same time, we are producer of
crystals.
It is a long and arduous process from seed crystal to the desired
single crystal, the composition of the crystal changes through
three states and eventually grows into beautiful crystals. We
witness the growth process of each crystal and clearly know
technologies of each step in the crystal growth process, which
means that we can directly provide customers with crystals that
satisfied customer requirements.
We create value. At same time, we link value.
From company to individual, we all pursue the word "value".
Individual is valuable in society, enterprise is valuable in the
industry. We cherish the existence of value. We hope to set the
enterprise’ value as start pointing, expand to the surrounding,
extend the value from the customer to the supplier. Linking
enterprise and the industry more closer, to create more value.
