Chongqing Research Better Science & Technology Co., Ltd (RBST for short) is a professional company specialized in high purity alumina series products researching, producing, marketing and technical supporting. Our high purity alumina is available in informs of powder, pellet/block, granule/ball and crystal. With innovated technology, our production process is superior to traditional process on impurities removing and stable purifying control. High purity alumina massive produced by our company is featured with stable high purity, low cost, good dispersion, high alpha phase inversion temperature, centralized particle size distribution as well as stable physical & chemical properties.

RBST has established good talent introduction and incentives policy that we now have more than150 employees, including 4 senior engineers, 8 engineers, 1 PhD, 3 postgraduates, 18 undergraduates. Our technical team has been in research and production of high purity alumina ever since 1997. We also have the most complete series of advanced testing and inspection equipment, like laser intensity instrument, ZETA potential instrument, the specific surface area and void instrument, true density meter, bulk density gauge, X-ray fluorescence spectrometer, X-ray diffraction and atomic absorption spectrometer etc., which strongly guarantees the process control and quality stability.

Our high purity alumina is widely used as raw materials in many fields, such as three color phosphor powder, thermal insulation electronic materials, LED sapphire wafer growing, high pressure sodium lamp as well as metal halide lamp etc..
