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。
