Description
Известна шахтна печь дл выращивани кристаллов методом Киропулоса, снабженна донным и боко:вым нагревател ми. Выращенные кристаллы диаметром 120-130 мм и высотой 15-20 мм имеют местами оптически непрозрачные участки. Это ухудщает качество люминофора .A known shaft kiln for growing crystals by the Kyropoulos method, equipped with bottom and side heaters. Grown crystals with a diameter of 120-130 mm and a height of 15-20 mm are sometimes optically opaque areas. This degrades the quality of the phosphor.
Предлагаема шахтна печь имеет керамическую диафрагму с центральным отверстием диаметром 40-50 мм. Толщина диафрагмы увеличиваетс от центра (2-3 мм) к периферии (12-15 мм). Диафрагма расположена на доннам нагревателе. Благодар этим отличи м повышаетс качество выращиваемых кристаллов.The proposed shaft furnace has a ceramic diaphragm with a central hole with a diameter of 40-50 mm. The thickness of the diaphragm increases from the center (2-3 mm) to the periphery (12-15 mm). The diaphragm is located on the bottom of the heater. Thanks to these differences, the quality of the grown crystals is improved.
Предлагаема шахтна печь предназначена дл выращивани кристаллов люминофоров NalTe и CsI(Te) диаметром 120-130 мм методом Киропулоса. Подобно извест-кой, она снабжена боковым и донным нагревател ми. Донный нагреватель имеет керамическую диафрагму , толщина которой в центре составл ет 2-3 мм и к периферии повышаетс до 12-15 мм. Диафрагма имеет центральное отверстие диаметром 40-50 мм. Применение диафрагмы позвол ет обеспечить равномерную скорость роста кристаллов, что дает возможность получить оптически прозрачные кристаллы диаметром 130 и высотой 60 мм с хорошими сцинтилл ционньши характеристиками.The proposed shaft furnace is designed for growing crystals of NalTe and CsI (Te) phosphors with a diameter of 120-130 mm by the Kyropoulos method. Like limestone, it is equipped with side and bottom heaters. The bottom heater has a ceramic diaphragm, the thickness of which in the center is 2-3 mm and rises to the periphery to 12-15 mm. The diaphragm has a central hole with a diameter of 40-50 mm. The use of a diaphragm ensures uniform crystal growth rate, which makes it possible to obtain optically transparent crystals with a diameter of 130 and a height of 60 mm with good scintillation characteristics.
