水热生长的合成石英中高的声损失严重地降低其可用性,特别是对于高频应用更是如此。早已知悉,声损失是与碱性生长溶液中以(OH)-形式进入晶格的间隙H~+有关的,H~+则是为了补偿晶格中Si~(+4)位置上存在的非正四离子(Fe~(+3)、Fe~(+2)、Cu~(+2)、Al~(+3))的。前已证明。为了抑制H~+的侵入(uptake)和提高Q,可从含Li~+盐的溶液中生长,因为这样使Si~(+4)位置上
The high acoustic loss of hydrothermally grown synthetic quartz severely reduces its usability, especially for high frequency applications. It has long been known that the loss of sound is related to the interstitial H ~ + entering the lattice in the form of (OH) - in alkaline growth solution. H ~ + is to compensate for the presence of Si in the lattice at (+4) Positive ions (Fe ~ (+3), Fe ~ (+2), Cu ~ (+2), Al ~ (+3)). Proved before. In order to suppress the uptake and increase Q of H ~ +, it is possible to grow from a solution containing Li ~ + salt, because in this way, Si ~ (+4)
