Abstract
Изобретение относитс к керамике и порошковой металлургии и может быть использовано при изготовлении плотных изделий из хрупких материалов. Цель изобретени - снижение трудоемкости и повышение достоверности. Способ предусматривает однократное прессование сухой навески монофракционного состава с соотношением максимального диаметра к минимальному 1,02-1,66 с последующим рассевом и пересчетом на плотную упаковку.The invention relates to ceramics and powder metallurgy and can be used in the manufacture of dense products from brittle materials. The purpose of the invention is to reduce labor intensity and increase reliability. The method involves a single pressing of a dry sample of a monofractional composition with a ratio of the maximum diameter to the minimum 1.02-1.66, followed by sieving and recalculated into a dense package.

Способ осуществл ют следующим образом .The method is carried out as follows.
Дп определени оптимального зернового состава керамической шихты (массы, смеси) исходный материал дроб т, подвергают помолу, путем рассева выдел ют монофракцию с максимальным диаметром, равным максимальному диаметру шихты-(массы, смеси), и соотношением максимального диаметра к минимальному, равным 1,02-1,66, Более широка гранулометри монофракции искажает картину полученной за счет дроблени естественной упаковки зерен . Сухую навеску вьщеленной монофракции засыпают в пресс-форму и подвергают статическому нагружению приDp determining the optimal grain composition of the ceramic charge (mass, mixture), the starting material is crushed, milled, monofraction is separated by sieving with a maximum diameter equal to the maximum diameter of the charge (mass, mixture) and the ratio of the maximum diameter to the minimum, equal to 1, 02-1.66, The wider monofraction granulometry distorts the picture obtained by crushing the natural packing of grains. A dry sample of the saturated monofraction is poured into the mold and is subjected to static loading at

Зна высоту прессовки и площадь ее основани , вычисл ют ее объем, а зна вес - кажущуюс плотность навески в пресс- форме.pressures 25, 100, 150 MPa. The height of the pressing is measured, the pressing is weighed and scattered into fractions. Knowing the height of the compact and the area of its base, calculate its volume, and knowing the weight, the apparent density of the sample in the mold.
Оптимальный зерновой состав шихты рассчитывают с учетом межзернового пространстваThe optimal grain composition of the mixture is calculated taking into account the intergranular space
