补充资料：晶体热释电效应
分子式：
CAS号：
性质：又称焦电效应。某些晶体由于结构上的不对称性，受温度变化引起某一结晶学方向上正负电荷重心的相对位移，改变自发极化状态，从而在该方向两边产生数量相等、符号相反的束缚电荷，即出现热释电效应。通常可分为两类：(1)具有自发极化，且自发极化不能为外电场转向的晶体，称为热释电晶体，如电气石、硫化钙、硒化钙、硫酸锂、氧化锌等；(2)自发极化可以为电场所转向的晶体，即铁电体，如硫酸三甘肽(TGS)、铌酸锂、钽酸锂、钛酸钡等。这些铁电晶体中的大多数可制成陶瓷(多晶体)，经极化处理后，能从各向同性体转变成各向异性体，并具有剩余极化，能像单晶体—样，显现热释电效应。由于陶瓷易加工，易于改性：成本低，是很有前途的热释电材料。利用晶体或陶瓷的热释电效应，可以制造红外热释电探测器、红外热释电摄像管等，在军事领域等已获应用。
