COMPOSITE MATERIAL BASED ON SIO2 MATRIX METHOD AND ITS RECEIPT

摘要

The invention relates to manufacturing technology scintillation detectors for registration of ionizing radiation for medical diagnostic equipment, custom systems, dosimetric and spectrometric devices. Composite materials based on SiO2 matrix consisting of an optical medium, which is SiO2 matrix, and activator-organic scintillator, which is the phosphor 1,2-bis (5-phenyl-2-oxazolyl) -benzolu (o-ROROR) or 2 5 dyfeniloksazolu (PPO), and the activator content is 3-5 wt. %. Also proposed method of composite material based on SiO2 matrix comprising solution for SiO2 matrix with a volume ratio of components tetrametoksysylan: methanol: water: monobasic inorganic acid is 1: 0.84: 1.2: 0.14, respectively, while stirring, transfusion resulting solution in sealed containers to hold the gel formation and drying it in the formation of the matrix, additional annealing the resulting matrix, the matrix impregnated within 24-48 hours. organic phosphor solution of 1,2-bis (5-phenyl-2-oxazolyl) -benzolu (o-ROROR) or 2.5 dyfeniloksazolu (PPO) in an organic solvent, concentration of the phosphor in a solvent 5-10 wt. %, Drying the resulting composite scintillator at a temperature of 40-50 ° C to mass constancy. Manufacturing of composite material that is claimed, does not require additional cleaning costs for raw materials, the use of the value of the growth equipment.
