Abrasives are substances both natural and synthetic that are used to grind, polish, abrade, scour, clean, or otherwise remove solid material usually by rubbing action (as in a grinding wheel), but also by impact (pressure blasting). The most important physical properties of materials that qualify as abrasives are hardness, toughness (or rigidity), grain shape and size, character of fracture (or cleavage), and purity (or uniformity). In the final analysis, the choice of a high-grade abrasive depends upon the quality and quantity of work performed by the abrasive per unit of cost. Initial cost of an artificial abrasive may be much greater than that of a natural abrasive, but the artificial mineral may do so much better work and do it so much faster than the ultimate cost is less. It is for this reason that artificial abrasives have largely replaced natural abrasives. Chemical Properties: Purities are available from PreRish Tri sometimes as high of a typical purity as 99.999% down to low purity recycled abrasive grains or powders Physical Properties: Numerous shape and size options are usually readily available from READE as large as 50 mm grinding and tumbling media down to as small as 20 100 nanometer particles. Typical Applications: Buffing, coated abrasives, coatings, deburring, electrical potting insulation, fillers, fining, flow finishing, friction, grinding wheels, heat transfer component, investment casting molds, wear resistant parts, metal lapping, polishing, pressure blasting, slurry sawing, tumbling, ultrasonic machining.

BaF2 window crystals or Barium Fluoride window crystals, with their extremely broad transmission range from the deep UV to LWIR spectrum, are prevalent for Infrared applications requiring additional transmission in the Ultraviolet region. BaF2 window crystals are excellent when being used for IR spectroscopes and as viewport windows for thermal imaging inspection in electric power facilities and petroleum industries. A low refractive index of 1.48 implies BaF2 windows have high transmission rates without anti-reflection coating. BaF2 window crystals has similar properties to CaF2, the difference mainly lies in that barium fluoride window is more resistant to highly energetic radiation, and with an equivalent thickness, the transmission range of BaF2 window extends approximately 1 micron further into the long-wave IR region than calcium fluoride. BaF2 window crystals could also accommodate high-temperature environments up to 800 â??. However, exposure to moisture will increase its sensitivity to temperature and reduce its transmission rate to UV lights.

OST Photonics offers various functional crystal materials for laser systems, optical equipment and instruments. Crystals are divided into six types according to their functions: laser crystals (diffusion bonding crystals, Nd:YAG, Er:YAG, Yb:YAG, CTH:YAG, Nd:Ce:YAG, Nd:YVO4, Nd:GdVO4, Nd:YLF, Pr:YLF, Ho:YLF, Tm:YLF, Ti:Sapphire, Er:Yb: Glass), nonlinear crystals (KDP & DKDP), KTP, LiNbO3, LBO, BBO, BIBO), passive Q-switch crystals (Cr4+:YAG, Co2+:MgAl2O4), birefringent crystals (YVO4, �±-BBO), Magneto-optic Crystals (TGG) and optical crystals (BaF2, CaF2, MgF2, LiF, Germanium single crystal, Sapphire (Al2O3), YAG, ZnSe, Silicon single crystal, ZnS). If you want to know more about our functional crystals, please do not hesitate to contact OST Photonics. What are Functional Crystals? A wide range of functional crystal materials is used in various optical applications. While optical glass is commonly used as a transparent material, different functional crystal materials, primarily monocrystalline materials, are required for diverse applications due to their unique functionalities: In contrast to glass, birefringent crystals can exhibit birefringence, which is a requirement for various types of polarizers, wave plates, birefringent tuners, and other optical components. Commonly used birefringent crystal materials include YVO4, �±-BBO, quartz, calcite and sapphire. The lattice symmetry of a crystal material is not too high (such as a triangular, quadrilateral, or single prism), and it can exhibit nonlinearity. Nonlinear crystals are primarily used for nonlinear frequency conversion but also find applications in optical modulators like the Pokel cell. A wide variety of functional crystal materials can be used as laser crystals, serving as host materials for laser-active dopants (rare earth ions or transition metal ions). They typically exhibit relatively high transition cross sections, small gain bandwidth, and good heat conduction compared to laser-active glasses. In general, they also allow for higher doping concentrations. In some cases, functional crystal materials are used in spectral regions where glass does not have a wide enough wavelength range and high transmittance. In particular, various materials such as zinc sulfide (ZnS), zinc selenide (ZnSe) and Sapphire (Al2O3) are used as infrared crystals, and other materials such as lithium fluoride (LiF), calcium fluoride (CaF2) and magnesium fluoride (MgF2) are used as ultraviolet crystals. Some functional crystal materials, such as terbium gallium garnet (TGG), exhibit the Faraday effect (polarization rotation caused by magnetic fields), and they can be utilized in devices like Faraday rotators and Faraday isolators.
1-SUDAN PIGEON PEAS Sudan Pigeon peas is cultivated in New Halfa area, Gadaref, Al Gazera and small areas of Kordofan and South Sudan, WHICH GIVES THE BEST AND SUITABLE ENVIROMENT OF TRPICAL CLIMATE, black cotton soil, well drained with a PH ranging from 7.0 - 8.5. AND 15-18�°C temperature It is sometimes known as the Congo pea or Gunga pea. Pea is a perennial legume from the family Fabaceae. Its cultivation can be tracked back more than 3,500 years. Also known as Adaseya or Lubiya in Sudan. The crop can maintain growth with poor soils and little water 2-GENERAL SPECIFICATIONS OF SUDANESE PIGEON PEAS ITEM DESCRIPTION MOISTURE 8% MAXIMUM PROTIEN 16% MINIMUM BROKEN GRAINS 1% MAXIMUM FORIEN MATTER 3% MAXIMUM 3-BENEFITS AND USAGE According to nutrition expert pigeon peas are excellent source of magnesium, phosphorus, calcium and potassium. The legume is rich in protein content and provides an adequate amount of iron, carbohydrates and fats that provides the human body with the energy needed to perform the functions of daily life. It also contains dietary fiber, potassium, vitamin B and C. Therefore, it is described as an afforded source for preventing anemia (iron), particularly for pregnant women, and the resulting neural tube defects in unborn tissues, muscles and bones and helps in curing joints and backbone pains. It helps in maintaining healthy heart and digestion (due to its fiber contents). Pigeon pea is as well known for its medicinal uses. Leaves are used as treatment of coughs, bronchitis, diarrhea, hemorrhages, sores, and wounds. Diabetes and sore throats can likewise be treated using other plant parts of pigeon pea As food. The Sudanese mainly use the boiled dry seeds. They add either sugar and fat or salt, with onion and sesame oil. Its consumption is related to the Muslim Holy Month of Ramadan, happy occasions and karama (alms organized as thanks giving to Allah). However, of recently, specialists are recommending expansion of pigeon pea use, particularly for school pupils and students boarding houses, as a cheap and equally rich nutritional source. Though it was first domesticated in India and grown there for thousands of years, still New Delhi has of recently started importing Sudanese pigeon pea due to its extra characteristics. Dried, pigeon peas are a main ingredient in Indian dals, Caribbean and African rice dishes, soups and stews. They are sometimes paired with green mango and fresh coconut. As beans, they need to be soaked and cooked for an hour or two. . .
