Ruibo Optoelectronics' revenue in 2015 was 110%, and its net profit increased by 106%.

On June 15th, Ruibo Optoelectronics (833810) recently released its 2015 annual report. As of December 31, 2015, Ruibo Optoelectronics' operating income was 109 million yuan, an increase of 124.51% over the same period of last year; net profit was It was 146.755 million yuan, an increase of 105.76% over the same period of last year.

As of December 31, 2015, Ruibo Optoelectronics' operating cost was 7,369,870 yuan, an increase of 130.81% over the same period of last year. The operating profit was 162.516 million yuan, an increase of 92.95%.

The revenue of Ruibo Optoelectronics in 2015 increased by 124.51% compared with the same period of last year, mainly due to the fact that during the reporting period, the new project of the main engine factory was put into production, and the sales revenue of Ruibo Optoelectronics for its supporting environmental atmosphere lamps doubled.

According to the data, Ruibo Optoelectronics mainly researches, develops, produces and sells electronic components such as car atmosphere lamps and sensors, and earns revenues to achieve profitability.

The Co-Al Co-doped Barium Titanate Lead-free Piezoelectric Ceramics was successfully developed by Yuhai company through repeated experiments. By Researching the influence of Co-Al Co-doping on the structure and properties of Barium Titanate-based piezoelectric ceramics, the formulation and preparation technology of Barium Titanate-based piezoelectric ceramics were optimized. Yuhai`s BaTiO3 was prepared by conventional solid-phase sintering method, with the piezoelectric constant d33 (>170pC/N), dielectric loss tgδ≤0.5% and mechanical coupling coefficient  Kp≥0.34.

Barium titanate lead-free piezoelectric ceramics are important basic materials for the development of modern science and technology, which was widely used in the manufacture of ultrasonic transducers, underwater acoustic transducers, electroacoustic transducers, ceramic filters, ceramic transformers, ceramic frequency discriminators, high voltage generators, infrared detectors, surface acoustic wave devices, electro-optic devices, ignition and detonation devices, and piezoelectric gyroscope and so on.

Application:  military, ocean, fishery, scientific research, mine detection, daily life and other fields.
