【摘要】 本文报导了用氨基甲磺酸部分取代硫酸三甘肽（TGS）晶体中的甘氨酸,生长出来的新晶体为硫酸三甘肽/氨基甲磺酸（AMTGS）。讨论了生长环境及其生长习性。进行了硫的元素分析,测定了晶体的介电和热释电性能。实验发现:AMTGS晶体易于生长,可以得到晶体外形类似于规则的斜方晶形的单晶体,在室温下,空间群仍为P2₁。AMTGS晶体具有较高的介电常数,因此其优值比TGS晶体稍低。更多还原

【Abstract】 Amino-methane sulphonic acid substituted triglycine sulfate(AMTGS) single crystals were grown. Crystal habits, chemical analyses, andferrelectric and pyroelectric properties are reported. It is found that thegrowth of AMTGS crystals is easy and crystals of regular form can be obtai-ned, when enough amino-methane sulphonic acid is added. As compared withthe TGS crystal, the AMTGS crystal has a higher pyroelectric coefficient anddielectric constant, and hence a slightly lower figure of merit.更多还原
