【摘要】 本文研究了玻璃的电场加热和磁场加热。熔融态的玻璃是离子导电体,故采用磁场加热更为合理。测定了玻璃的高温电阻率,确定了磁场加热的有关参数。建立了6升坩埚的高频熔炼装置,制备了一批优质激光玻璃棒。实验结果表明高频熔炼的优越性,它可用于制备激光玻璃和其他高纯特种玻璃。更多还原

【Abstract】 In this article, electric and magnetic field heating techniques for melting laser glassesare studied. The use of magnetic field heating is suitable because melting glass is anionic electric conductor. The resistivity of laser glasses at high temperature is measured,the parameters associated with magnetic field heating are determined. A radio frequencymelting equipment with a 6 litre crucible has been built, and the laser glasses rods ofhigh quality have been made. Experimental results show some advantages of the radio fre-quency melting. This technique can be used to produce laser glasses and other specialglasses of high purity.更多还原
