直径为6英寸(151毫米)、长度为770毫米的半导体材料—区熔硅单晶,日前由天津市环欧半导体材料技术有限公司研制成功。这是我国所能研制的最大直径区熔硅单晶。区熔硅单晶是硅单晶的一种。大功率振荡管主要用于重型电力拖动装置如机车、战车和舰船的高频调速,巨型水力、火力发电站的远距离、超高压交、直流变电,高频、中频炉, The diameter of 6 inches (151 mm), a length of 770 mm semiconductor material - zone melting silicon single crystal, a few days ago by the Tianjin Central Europe Semiconductor Materials Technology Co., Ltd. successfully developed. This is our country can develop the largest diameter of fused silicon single crystal. Zone melting silicon single crystal is a kind of silicon single crystal. High-power oscillation tube is mainly used for heavy-duty electric drive devices such as locomotives, tanks and ships of high-frequency speed control, giant hydraulic and thermal power station long-distance, UHV AC, DC power, high frequency,
