Hanhua Si Industry Ltd.

Specialized in quartz purifying and miniaturization, Hanhua Si devoted ourselves years in the laboratory implementing scientific researches. Made technological breakthrough, we’ve accumulated numerous valuable data for the large-scale production and our products are in accordance with the international criterion. Came into operation in 2015, Hanhua Si Industry Ltd. is occupying a ground space of 70,000 ㎡ with the total investment of $30 million, our factory produces high-tech Silica products including ultrahigh-purity silica powder with SiO2 purity ≥ 99.999%, high-purity ultra-fine silica powder with the particle size of nano-meter level and spherical high-purity silica powder. We are probably the only company in China who can produce this purity and fineness of the SiO2 products and we've been authorized by PRC Ministry of Science and Technology. Our global business intersperse among North America, EU and Asia. Now we are sincerely looking for experts to work for our European R&D Centre. 1. SiO2 purification technique which can be able to purify silica powder from quartz for the SiO2 purity above 99.9999%. Technique is environmental friendly needed. 2. Ultra-fine spherical silica powder making technique for the spherical rate above 98% and fineness of both micrometer and nanometer level. Technique need to be physical method, environmental friendly and the quantity of output can be above 1000t each production line per year. 3. High-purity large-sized quartz-glass making technique. 4. Electronic packaging materials making technique which in usage of ISI, VLSI and LED by the material of ultra-fine quartz powder. 5. Invisible coating making technique. We accept any kind of co-operations. Contact: Gabriel International Business Development Executive Email: [email protected]
