先进的高压Bridgman-Stockbarger炉滚刀，能够在1100°C和300 bar氧分压下生长晶体
Bridgman-Stockbarger炉HOB是一种开创性的晶体生长系统，专为1100°C温度下300 bar的高压氧气应用而设计。这个复杂的垂直炉包括两个独立控制的加热区，每个加热区长度为160毫米，以及一个内部工艺室，为适应高氧分压下晶体合成的苛刻要求而量身定制，达到300巴纯O2。该炉解决的一个重大挑战是高氧分压和高温以及导电加热元件的结合。针对这些挑战，我们的解决方案包括将工艺空间与加热元件空间严格分离，并对压力容器进行有效冷却。这是通过冷压力容器内的两个气密隔间实现的。加热元件在惰性氩气环境中工作，而工艺室则充满高压氧气。自动压力调节确保两个隔室在加热或冷却过程中始终保持相同的压力，因为压力容器内的热气体屏障无法承受压力差。设计中集成了多种安全机构，确保了外压力容器壁的稳定性。这种设计不仅确保了有效的热量分配，而且还排除了加热材料氧化的风险，这对于恶劣的操作条件至关重要，并确保了加热元件和压力室的最大使用寿命。该炉在悬挂坩埚或直径达18毫米的密封石英管中促进有效的晶体生长。该设计可容纳拉动和旋转驱动，使坩埚或密封石英管在晶体生长过程中实现垂直运动和旋转。控制速度可以设定在0.1毫米/小时和100毫米/小时之间。坩埚的安装和拆卸可以在炉膛下方的自由空间内轻松完成，只需将拉拔驱动器的末端从下加热区拉出即可。该炉支持先进的PID温度控制，允许在两个区域进行精确的热管理，从而促进各种晶体材料的最佳生长条件。在与用户密切协商的情况下，我们提供了为系统配备额外功能的选择，并在炉组件和软件方面不断适应新的要求。该Bridgman-Stockbarger炉HOB是一个理想的解决方案，为研究人员和制造商寻求一个可靠和有效的平台，先进的晶体生长在高压氧气环境，结合精度，安全性和易于操作。
