(名詞) 冰葬 － 將遺體放入攝氏零下 196 度的液態氮 (liquid nitrogen) 中急速冷凍、乾燥並粉化。這是近年來國外殯葬業積極推動的一種嶄新的下葬方式，過程不僅快速、費用低廉，而且最重要的是對環境友善。經過機器粉化的骨灰在取出任何金屬物 (如假牙或其他植入物) 之後還可當植物的肥料，對環保做出貢獻。
Cryomation 原為一家同名公司已取得專利的下葬方式，又叫做 promession。這個字是由 cryogenic (低溫的) + cremation (火葬、火化) 拼綴而成。
Cryomation or promession is a novel technique that involves immersing a body in liquid nitrogen down to a temperate of -196ºC at which point it becomes extremely brittle. Pressure then fragments the body into small particles allowing for the removal of any surgical implants and other foreign material.

But trends in the funeral industry are beginning to shift as new and reconceived rituals, designed to be more culturally and environmentally sustainable, come into public awareness.
“We’re hearing these new words starting to emerge from the field; one is aquamation, a cremation done with water,” explains Dr Interlandi.
“Or you’ve got cryomation, where the body is actually submerged in liquid nitrogen and crushed afterwards.”
