Description
タンタル酸リチウム単結晶の温度変化に伴って形成する高電場を電場触媒反応に応用することを目標とし,反応基質を導入可能な密封系小型高電場発生ユニットを製作した.z軸長に対するz面の面積が異なる二種類の単結晶を用いてX線発生実験を行ったところ,単位z軸長あたりの生成した電場は薄片型結晶の方が大きかった.単結晶表面に白金箔を添加した状態でも,白金箔の特性X 線が最高エネルギー22 keV の白色X 線に重なって観測された.製作した密封空間のガス放出挙動を質量分析計で測定した.
Description Alternative
Compact devices for high electric field generator using a different aspect ratio of pyroelectric LiTaO3 single crystal and a Peltier device were assembled. Measurement of X-ray emitted upon the thermal changing was carried out to evaluate the induced electric field onto surface of the z-plane of LiTaO3. The formed electric field per length of the z-axis for thin-type (10 × 10 × 2 mm) was twice larger than that of pillar-type (3 × 3 × 10 mm). The attachment of Pt foil onto the surface of z-plane little affected on X-ray emission behavior. The flange-type generator with thin-type LiTaO3 single crystal was also assembled to construct a reactor for chemical reactions with induced high electric field of a pyroelectric crystal. The outgassing behavior from a reaction vessel was examined.
