通过在300开尔文下将AlPO 4 berlinite单晶压缩到18吉帕斯卡，已经产生了表现出结构记忆的玻璃。这种玻璃的独特和非凡的特性是，当减压低于5吉帕斯卡时，它会转变回与初始晶体相同取向的单晶。这种玻璃对形成它的晶体的先前晶体学取向具有“记忆”。
A glass exhibiting structural memory has been produced through the compression of a single crystal of AlPO4 berlinite to 18 gigapascals at 300 kelvin. The unique and extraordinary characteristic of this glass is that upon decompression below 5 gigapascals it transforms back into a single crystal with the same orientation as the starting crystal. This glass has a "memory" of the previous crystallographic orientation of the crystal from which it forms.
