Natural sapphire

Natural saphire is known as a valued blue gemstone. The blue color is caused by the presence of Ti and Fe or other defects in the aluminium oxide matrix.

Synthetic sapphire is, on the contrary, extremely pure and defect-free aluminium oxide single crystal.

Sapphit™ - the true jewel of industrial and scientific instruments

Sapphit™ is a single crystal of Al2O3 that is forced to crystalize into the desired shape/profile by Crytur‘s proprietary and patented technology.

Sapphit™ is the result of the state-of-the-art manufacturing process involving material tempering, which minimizes any inner tension and guarantees perfect material homogeneity. Sapphire crystallization

Sapphit™ structure is perfectly homogenous with molecules arranged into a perfect crystal lattice throuhout the whole product leaving no weak points to be attacked.

Ceramic materials compose of microscopic grains. Grain boundaries represent structural weak points and source of impurity due to the residue of sintering material.

Sapphit™ - single Al2O3 crystal

Not only by structure but also by chemical purity is Sapphit™ a far superior product to alumina ceramic.

SAPPHIT™ Ceramics

Corrosion resistence Perfect

No signs od corrosion after 2 years in the corrosive environment

Low

Destroyed after 5 month in the same environment

Shape stability Perfect No changes in shape until reaching the metling point

LimitedHigh temperatures may cause deformation

Durability HighHardness just below diamond guarantees that the material is not weared

LimitedSome corrosive oxides can even penetrate through the sintered ceramics.

Temperature resistence Up to 2000°C (3632°F) Up to 1800°C (3272°F)

Gas tightness 100% gas-tight, very high pressure resistance

Limited and dependable on manufacturer/model

FOR TEMPERATURE MEASUREMENT

Sapphit™ is the material of choice for the protective casing of thermocouple probes.

For its material characteristics Sapphit™ protective sheaths present an efficient alternative or combination to commonly used materials - large variety of corundum ceramics or platinum coated sheaths

To ceramics, Sapphit™ is a far more durable product

Patented solution – Patent No. CZ302212 (2006)

Higher safety – low manipulation frequency also significantly decreases the risk of injuries in production processes with intensive heat environments.

Handling comfort – no extra handling once mounted, long service of Sapphit™ termocouples reduces handling to minimum

Outstanding physical properties - high temperature and pressure resistance together with perfect chemical stability delivers the best performance in heavy duty operations

Benefits of of Sapphit™ protective sheaths

Longer service life – compared to sintered ceramics, Sapphit™ casings survive much longer in identical conditions

Less shutdowns – longer service life of Sapphit™ casings leads to a reduced amount of process shutdowns due to thermocouple malfunction, in some processes Sapphit™ thermocouples outlast the service life of the device in which they are mounted

FOR TEMPERATURE MEASUREMENT

Sapphire thermocouples deliver the best performance in harsh processes:

• Concentrated or boiling mineral acids• Reactive oxides at high temperatures• Ammonia synthesis• Claus process• Gasification • Desulphurization• NOx removal• Flying ash attachments• Floating non-metal melts

Sapphire’s strength, temperature stability, purity and 100% gas-tightness as a single crystal guarantees that this material can be used as an inert construction material to insulate furnace heated zones at temperatures as high as 1900 °C. Sapphire tube furnaces can be designed as an ideal cost-effective solution for reaching high vacuum or to perform annealing in inert, oxidizing or even reducing (hydrogen containing) atmospheres at high temperatures.

Flexibility and contamination-free operation are yet further advantages of this solution. Its composition (4N Al2O3) means that it finds applications even in semiconductor manufacture. Most importantly, sapphire tubes can be easily taken out and if necessary, easily cleaned with strong oxidizing solutions or, for example, with boiling mineral acids like aqua regia or hydrofluoric acid. Several sapphire tubes can be employed and exchanged where flexible clean annealing of various components is required. As such, this solution is also ideal for small laboratory set-ups.

Sapphire can effectively encapsulate any metal or ceramic heating element in such a way that no contamination occurs, as well as having the heating wire covered with protective atmosphere. The heating element can be in the shape of a single wire closed within a sapphire tube, or in the form of a metal spiral in between two sapphire tubes, effectively creating a tube furnace.

Sapphire is and ideal material for protection of heating elements against harsh environment and extending them life-time. Sapphire tubes can be used up to 1900°C and can keep heating element under innert or reductive atmosphere. Sapphire allows to enclosure tungsten or molybdenum heating elements and use them under oxygen. Sapphire is pure Al2O3 (99,995%)

Sapphire tubes are offered in standard diameters from 1,0 mm up to 44 mm with length up to 2 m.
