High-purity quartz sand purification, two latest breakthroughs!​



Two quartz purification technology-related patents of Zhejiang Runyou New Materials Co., Ltd., namely "A microwave magnetic roasting-gradient magnetic separation iron removal method and purification process for quartz ore" and "A feldspar -quartz flotation combined collector and application method". A microwave magnetization roasting-gradient magnetic separation iron removal method and purification process for quartz ore The invention relates to a microwave magnetization roasting-gradient magnetic separation iron removal method and purification process of quartz ore. First, impurity minerals/inclusions in the ore are magnetically modified by microwave magnetization roasting, and weak magnetic minerals in the quartz minerals are converted into strong magnetic minerals by using a gaseous reducing agent to avoid the introduction of solid impurities. At the same time, Fe-containing gas-liquid inclusions are heated and decomposed at a specific temperature and magnetically converted, and then the magnetic minerals are removed by a permanent magnet-high-intensity superconducting magnetic separation gradient magnetic separation process to obtain low-iron quartz sand. Due to the characteristics of microwave selective heating, gas/solid inclusions are more likely to break and be exposed to the outside world, which effectively improves the efficiency of subsequent impurity removal and purification. With the help of purification processes such as acid leaching, flotation, and chlorination roasting, high-purity quartz sand with Fe≤0.05ppm and SiO2≥99.998 % can be obtained . The method of the invention can remove ferromagnetism, weak magnetic impurities and inclusions in quartz sand in a targeted manner, and has an excellent iron removal effect, a simple and efficient process, and is more environmentally friendly.​

nice, so this looks like another 4N8 purity, which is good enough for the semiconductor crucibles, right?

For a lot of this, it seems like they just need to ramp up production now.

Total investment of 2.2 billion! BOE's photomask joint venture project starts shipping.​


It is understood that Chongqing Matt Optoelectronics Co., Ltd. was jointly funded by HOYA Co., Ltd. and BOE Group. It is the first large-scale photomask production equipment investment project in inland China by a photomask manufacturer in the world, with a total investment of 2.2 billion yuan, and plans to achieve full-load production in 2027. After full production, the annual production capacity is expected to reach about 2,250 photomask products, with an output value of 700 million yuan.

Chen Yanshun , Chairman of BOE Technology Group , said that BOE has successively implemented 8 major projects in Chongqing, helping Chongqing to accelerate its development into an important global semiconductor display industry cluster. BOE has a good history of cooperation and close relations with Japanese companies. In 2022, it joined hands with the world-renowned mask manufacturer Hoya to jointly invest in the Matt Optoelectronics photomask project, opening a new chapter of high-quality cooperation in the semiconductor display industry between China and Japan. It is another important milestone for BOE to promote industrial cooperation between China and Japan. The project focuses on the production of key components and photomasks in display panel manufacturing. It aims to build the world's number one photomask supplier by bringing together BOE and Hoya's top resources in the field of global display products and mask manufacturing, and jointly promote the high-quality development of the display industry and the local economy.
