Abstract
1. Способ получения пористого керамического материала на основе пирофосфата кальция, включающий подготовку шихты, формование и обжиг, шихта при этом содержит фосфат кальция и компонент, обеспечивающий формирование пористой структуры при термообработке, отличающийся тем, что шихта содержит фосфат кальция с мольным соотношением Ca/P в интервале 0,9-1,1, синтезированный соосаждением из растворимых солей кальция и растворимых фосфатов, дающих легкоудаляемые при термообработке сопутствующие продукты реакции, в качестве компонента, обеспечивающего формирование пористой структуры, используют дигидрофосфат натрия, который при подготовке шихты смешивают с фосфатом кальция при соотношение по массе «фосфат кальция/дигидрофосфат натрия» в интервале 63/37-67/43, а обжиг проводят при температурах в интервале 800-900°C в течение времени, обеспечивающем формирование пористого материала.2. Способ по п.1, отличающийся тем, что обжиг осуществляют в течение 1-3 ч.1. A method of obtaining a porous ceramic material based on calcium pyrophosphate, including the preparation of the mixture, molding and firing, the mixture contains calcium phosphate and a component that provides the formation of a porous structure during heat treatment, characterized in that the mixture contains calcium phosphate with a molar ratio of Ca / P in the range of 0.9-1.1, synthesized by coprecipitation from soluble calcium salts and soluble phosphates, giving accompanying reaction products that are easily removable during heat treatment, as a component, I provide For the formation of a porous structure, sodium dihydrogen phosphate is used, which is mixed with calcium phosphate when preparing the charge with a weight ratio of calcium phosphate / sodium dihydrogen phosphate in the range of 63 / 37-67 / 43, and firing is carried out at temperatures in the range of 800-900 ° C during the time providing the formation of porous material. 2. The method according to claim 1, characterized in that the firing is carried out for 1-3 hours
