Import Bgo Scintillator — Buy in Bulk from Supplier in China

Bismuth germanate (Bi4Ge3O12, BGO) is a high-density oxide scintillation crystal prized for its stopping power and radiation hardness in gamma-ray and particle detection systems. Epic Crystal Co., Ltd. supplies BGO scintillators with a stated density of 7.13 g/cm³ and radiation length of 1.12 cm, physical properties that enable compact detector geometries with high gamma-ray absorption efficiency. The 300 nanosecond decay constant positions this material in the intermediate speed category among oxide scintillators, slower than cerium-doped materials but acceptable for applications where timing resolution is secondary to detection efficiency and energy resolution. The emission peak at 480 nm falls within the high sensitivity region of standard photomultiplier tubes and silicon photomultipliers, facilitating straightforward optical coupling without exotic readout devices.

BGO crystals are grown by the Czochralski method from stoichiometric melts of bismuth oxide and germanium oxide, a process demanding precise atmosphere control and crucible material selection to minimise colour centres and radiation-induced absorption. The 7.13 g/cm³ density exceeds that of NaI(Tl) and approaches lead glass alternatives, making BGO advantageous for space-constrained geometries such as borehole logging tools, positron emission tomography ring detectors, and high-energy physics calorimetry. The 480 nm emission wavelength matches well with bialkali photocathodes, though the material exhibits moderate light yield compared to LSO:Ce or LaBr3:Ce alternatives, typically achieving 15-20% of NaI(Tl) absolute light output. Standard crystal dimensions range from small cylinders and rectangular prisms for spectrometry to large blocks exceeding 50 mm per side for calorimetry, with optical polishing and Teflon wrapping or diffuse reflective coating to maximise light collection uniformity.

Primary buyers include nuclear physics research institutions, medical imaging equipment manufacturers, oil and gas well-logging service companies, and industrial radiation gauging system integrators. BGO's radiation hardness and absence of hygroscopicity distinguish it from NaI(Tl) and CsI(Tl) alternatives, permitting operation without hermetic encapsulation in many configurations. Epic Crystal Co., Ltd. operates from Shanghai's Pudong district, though specific lead times, minimum order quantities, and pricing are not disclosed in available data and require direct confirmation. The supplier's 0.00% response rate indicates buyers must independently verify communication channels and current production capacity before relying on quoted delivery schedules.

Epic Crystal Co., Ltd. is located at No 100, Jinyu Road in Shanghai's Pudong Area, a district that hosts both advanced materials research facilities and manufacturing operations serving the optics and crystal growth sectors. The company holds an imported supplier tier and harbor trust tier classification, indicating a basic marketplace listing without advanced third-party verification. With a 0.00% response rate and zero average response hours recorded, the supplier's communication reliability cannot be assumed, and buyers must take proactive steps to confirm the company's current operational status and willingness to engage on technical enquiries before committing to purchase orders.

The supplier profile does not disclose founding date, employee count, annual production capacity, ISO quality management certification, or specific clientele in the radiation detection sector. No factory audit reports, export licence details, or intellectual property holdings are mentioned. The source description presents Epic Crystal Co., Ltd. as a manufacturer of BGO scintillation crystals, but the extent of in-house crystal growth versus trading operations is unclear from available data. Buyers should request the company's business licence, any available crystal characterisation data such as light yield uniformity maps or radiation damage test results, and references from existing customers in the nuclear instrumentation or medical imaging industries to assess technical credibility.
