Material Demand of Sapphire Crystal Industry in China (I)

                                              Material Demand of Sapphire Crystal Industry in China (I)

The sapphire crystal industry mainly has two market segments, namely the sapphire crystal material market and the sapphire crystal product market. Among them, sapphire materials are divided into sapphire crystal, sapphire crystal bar, sapphire raw stone, etc. As an important technical crystal, sapphire crystal has been widely used in many fields such as science and technology, national defense and civil industry, and electronic technology, such as infrared window materials, substrate substrates in the field of microelectronics, laser substrates, optical components, and other applications; Sapphire crystal is aluminum oxide crystal, which is used to produce sapphire substrate, and sapphire substrate is the basic material of LED lighting; Sapphires are mostly processed into jewelry.

1、 Application field

After sapphire crystal has been widely used, sapphire products have also developed rapidly. In the traditional sense, sapphire crystal mainly appears in front of the world as a handicraft and jewelry, and occupies a high position in the hearts of consumers. However, with the development of scientific research and technology of sapphire crystal, the popularity of sapphire crystal has come, and various products have gradually penetrated into all aspects of life. At present, sapphire crystal products mainly include sapphire glass, sapphire screen, sapphire lens protection glass, sapphire jewelry, etc.

 In terms of sapphire crystal market, LED substrate is an important application of sapphire crystal zui, and it is now in a dominant state. However, with the continuous development of sapphire crystal in the field of consumer electronics, new growth points will emerge. For example, if all smart phones use sapphire covers, the demand for sapphire crystals will grow by leaps and bounds, and further bring about broad market demand in the sapphire industry.

Sapphire is mainly used as the first choice of LED upstream substrate materials in the LED field, on the one hand, because of the existing expertise Industrial knowledge and production equipment are relatively matched with sapphire production. On the other hand, sapphire crystal has low cost and strong availability, which can produce cheap LED products.

With the continuous popularization of LED applications, especially the explosion of LED lighting market, which has driven the rapid development of LED industry, sapphire crystal substrate, as an important raw material of LED chip zui, has also ushered in a golden period of demand. In 2018, the global market size of sapphire for LED was about 3.7 billion dollars.
