一、总論压电石英是指那些能取得單晶塊的三方晶系的水晶,就我国的情况而言,是指沒有缺点的(双晶、节瘤、包裹物等),塊度为1.2×1.2×1.2公分的晶塊。人們利用压电石英,不是利用它的SiO_2成分,而是利用它的結晶性質。因此在研究压电石英矿床时,不仅要考虑它的地球化学特点,而且也要考虑它的結晶化学特点。 First, the general piezoelectric quartz refers to those who can get single-crystal cubic crystal system, in our case, refers to no flaws (twins, knots, wraps, etc.), the block size of 1.2 × 1.2 × 1.2 cm block. People use piezoelectric quartz, not to use its SiO 2 composition, but to take advantage of its crystalline nature. Therefore, in the study of piezoelectric quartz deposits, not only to consider its geochemical characteristics, but also to consider its crystallization chemistry.
