Изобретение относитс к аналитической химии , а именно к способам разложени проб цирконийсодержащих огнеупоров и керамики, и может быть использовано при аналитическом конт- s роле производства цирконийсодержащих материалов.The invention relates to analytical chemistry, namely to methods for decomposing samples of zirconium-containing refractories and ceramics, and can be used in analytical control of the production of zirconium-containing materials.
Цель изобретени - повьшение точности и упрощение анализа.The purpose of the invention is to increase the accuracy and simplify the analysis.
Пример . Навеску пробы оксид- 10 ноциркониевой керамики 0,15 г, истертой до размера не более 0,063 мм.An example. A weighed sample of oxide-10 nozirconium ceramics 0.15 g, worn to a size of not more than 0.063 mm.

помещают в аналитический автоклав, добавл ют 10 мл 9 М раствора сол ной кислоты, 1,5 г хлорида натри (3 М раствор). Автоклав закрьшают герметично и выдерживают при 270°С в течение 3 ч. После растворени пробу перенос т в мерную колбу на 200 МП и довод т до метки дистиллированной водой. Данные разложени цирконийсодержащих проб предлагаемым способом при различных услови х .приведены в таблице. Iplaced in an analytical autoclave, 10 ml of a 9 M hydrochloric acid solution, 1.5 g of sodium chloride (3 M solution) are added. The autoclave is closed tightly and kept at 270 ° C for 3 hours. After dissolution, the sample is transferred to a 200 MP volumetric flask and brought to the mark with distilled water. Data on the decomposition of zirconium-containing samples by the proposed method under various conditions are given in the table. I
