【摘要】 介绍了用激光脉冲法对热压Z nS(硫化锌)靶材的比热容、热导率测试和ZnS靶材线膨胀系数、抗弯强度测试方法的研究.试验证明:热压ZnS靶材有较好的热导率,在C D-R W(可读写光盘)的上下介电层应用上为记录层提供了很好的散热效果;ZnS靶材的线膨胀系数较低,有很好的尺寸稳定性;ZnS靶材有一定抗弯强度.更多还原

【Abstract】 The paper introduced determination on specific heat capacity and thermal conductivity of Hot Pressing ZnS target material by laser flash process;Moreover introduced measuring method for line expansion coefficients and bend strength of HP ZnS target material. ZnS target material possessed better thermal conductivity property,which provided very best radiating effect for record layer in CD-RW up and down dielectric layer application. ZnS target material has lower line expansion coefficients,very best size stability and fair bend strength.更多还原
