METHOD OF MANUFACTURE OF MICROCHANNEL PLATES WITH MONOLITHIC FRAMING Russian patent published in 2003 - IPC

FIELD: treatment of glass fibers by sintering; electro-optical transducers. SUBSTANCE: proposed method includes assembly of multi-core light conduits in unit, sintering at simultaneous reduction and imparting pressure at heating frame on base of lead-silicate glass. Sintering is performed at temperature of 580-600 C continued for 0.5-1.0 h and followed by annealing at temperature of 475- 485 C continued for 3.5-4.5 h and followed by cooling to temperature of 360-380 C at rate of 0.5 C/min; cooling to surrounding temperature is effected in inertial mode. EFFECT: enhanced mechanical strength; improved quality of plates; increased yield of plates. 1 tbl, 1 ex
