The chemical composition of sapphire is aluminum oxide (Al 2 O 3 ), which is blue due to the trace element titanium (Ti 4+ ) or iron (Fe 2+ ). It is a trigonal system. The shape of the crystal is often cylindrical, short column, plate, etc., and the geometry is mostly granular or dense. Transparent to translucent, glass luster. The refractive index is 1.76-1.77, the birefringence is 0.008, and the dichroism is strong. Heterogeneous. Sometimes it has a special optical effect - the starlight effect. The hardness is 9, and the density is 3.95-4.1 g/cm 3 . No cleavage, crack development. Under certain conditions, beautiful six-shot stars can be produced, known as "star sapphire." Sapphire can be divided into blue sapphire and brilliant (non-blue) sapphire. The color is best in the Indian cornflower blue. Sapphire is said to protect the king and the monarch from harm, and is known as the "stone of the emperor." The international gem world has designated sapphire as "the birthstone of September", symbolizing love, loyalty and firmness. Sapphire is one of the world's top five precious high-end gemstones. Evaluation and purchase of sapphire. The evaluation and purchase factors of sapphire are color, weight, transparency and clarity. The biggest feature of sapphire is that the color is not uniform, the polycrystalline twin crystal is not developed, and the dichroism is strong. The sapphire produced in Myanmar is bright blue (including titanium coloration), which can produce six or twelve stars due to inclusions. Indian Kashmir sapphire, blue cornflower, is a micro-purple purple indigo, bright color, is a high quality sapphire. Sapphire produced in Sri Lanka, Thailand, China and Australia also has its own characteristics. Sapphire is brittle and should be worn and bumped when worn.
Intergrated Design Batch Waste Plastic Pyrolysis Plant
Pyrolysis Plant is used for recycling waste tire, waste plastic, waste rubber to fuel oil. According to the actual situation in every country and district, we developed different models of Batch Pyrolysis Plants for waste tires, rubber and plastic with daily capacity 5 -10 tons.
