Method of ashes preservation by hydroxylapatite ceramic

Abstract

The present invention discloses a method of ashes preservation by hydroxyapatite ceramic. The invention is characterized by sintering the ashes at a high temperature, and curing the ceramic, thereby reducing the storage volume of the ashes, reducing the amount of heavy metal ions dissolved out, and preventing the ashes from becoming mildewed and being polluted by microbes. The method of ashes preservation by the ceramic can be widely used for processing various ashes, and can also be used for preparing the ceramic of ashes according to the figure and the appearance of a dead person during the dead person's lifetime, so as to cherish the memory of the dead.

Description

technical field [0001] The invention relates to a method for preserving ashes with hydroxyapatite ceramics in the funeral field. Background technique [0002] Cremation is one of the main ways to deal with human remains in my country at present. As of 2009, the cremation rate in my country has reached 60%, and the annual output of ashes is 5 million. With the continuous development of funeral reform, the cremation rate will increase year by year, and the production of ashes will also continue to increase. my country has a population of more than 1.3 billion. Calculated according to the average life expectancy of 80 years, 16 million people die every year on average. Calculated according to the cremation rate of 60%, 10 million ashes will be added every year. [0003] The current methods of handling ashes are mainly stored in columbariums or columbaria, in addition to burial in cemeteries, scatter in the sea, and scatter in the river. The columbarium or columbarium storage ...

Problems solved by technology

[0004] The purpose of the present invention is to propose a method for preserving ashes with hydroxyapatite ceramics. Ceramics preserve ashes to overcome the large area and cost of depositing in existing columbariums or columbariums, burying them in cemeteries, spreading seas and rivers, etc. High disadvantages, high temperature can completely decompose carbon and other volatile organic compounds, make the ashes lose organic nutrients, and prevent the ashes from mildew
