Development Status of Superhard Materials in Henan Province

China is a big producer and exporter of super abrasives, and the production of superhard materials has accounted for more than 90% of the world, which has the absolute advantages. Superhard material industry in China has changed the world superhard material industry pattern, to become the world's one of the leading forces of superhard material industry.

In the development of superhard material industry in China, Henan always plays a guiding role, which is a strong force in this industry, with a series of advantages, such as research and development, technology, information, market and industry service management of superhard material industry.

Synthetic diamond

In 1954, GE Company used ultra-high pressure high temperature technology to synthesize the world's first synthetic diamond in the United States. In 1957, they used the diamond for the first time for grinding carbide and glass, which is a pioneer in the massive and global development of superhard abrasive industry today. China's first synthetic diamond was successfully developed in 1963. After more than 50 years of development, the production of synthetic diamond is increasing rapidly in China, from  10000 carats of the annual output in 15.1 billion carats in 2013, accounting for about 90% of the world's total output of diamond. The synthetic diamond industry is the key support industry of new material industry development plan.

Henan province is the most concentrated area of synthetic diamond and its products enterprises, and is equipped with the only state-level superhard material industry base of China. The domestic main synthetic diamond production enterprises are basically concentrated in the territory of Henan province, which are mainly distributed in Superhard Materials and Products Industrial Park of Zhengzhou High-tech Development Zone and the Yellow River Synthetic Diamond City in Xuchang and other production bases in Nanyang, Sanmenxia, etc. The sales of synthetic diamond in Henan province always rank the first, and in 2013, the production of synthetic diamond in Henan province accounts for more than 80% of the country's total quantity, which has obvious regional characteristics.

Among many synthetic diamond suppliers,  Boshi Superhard Material Co.,Ltd., Yuzhou He Hui Superabrasives Co.ltd.,  Jinxin Abrasives Co.,ltd., Xinren Superabrasives Co,.limited, and Beijing Xin Bai Bentley Superhard Materials Co., Ltd. are all professional suppliers that can not only supply high quality synthetic diamond but also offer professional after-services for buyers, so their products are popular with buyers on iAbrasive.com.

Cubic boron nitride (CBN)

Cubic boron nitride (CBN) abrasives are superhard abrasive varieties with synthetic diamond abrasives almost born around the same time. In 1957,R. H. from the United States first developed it successfully. Zhengzhou Research Institute for Abrasives & Grinding took the lead to create the China's first CBN in 1966, which opened the prelude of CBN research and industrial production. CBN synthesis technology in China has achieved rapid development in recent years, we not only become the CBN production country, but also are CBN production power.

From the point of the world CBN market development, the demand of CBN is growing at more than 18% every year. CBN in China accounts for 60% of the world output, whose product quality has reached or been close the world's advanced level. And the products have been exported to all over the world and are widely recognized, which enjoys the discourse power in the world market.
