應用：
1. 晶體硼在核工業的應用：
Crystalline boron plays a crucial role in the nuclear energy field. It can be used as a neutralization control material in nuclear reactors. Boron can compensate for and regulate neutralization reactivity and to facilitate emergency shutdowns. Thus maintains stable reactor operation. Crystalline boron not only has a high neutralization absorption cutoff but also a wide range of neutralization energy absorption, effectively reducing or regulating the neutralization flux generated by nuclear energy. Thereby it ensures the safety of the nuclear energy system.
2. Applications of Crystalline Boron in Semiconductor Manufacturing:
Crystalline boron is also widely used in the semiconductor industry. As a p-type dopant, crystalline boron can be used to modify the conductivity of semiconductor materials. By doping crystalline boron into silicon Ingot, the conductivity properties of silicon can be altered. Then manufacture semiconductor devices with different conductivity types, such as diodes and field-effect transistors. In addition, crystalline boron can also be used as a raw material for growing long-lasting semiconductor single-crystal materials. Boron-doped silicon single crystals can be grown using a melt-blown method for fabricating high-performance semiconductor devices.
99.9% purity crystalline boron powder is used in the production of solar silicon wafers as a substrate dopant for P-type silicon wafers and as a boron emitter diffuser for N-type silicon wafers. High-purity boron powders of 5N and 6N can be used as dopants for P-type semiconductors to alter their conductivity and are used in the production of high-purity silicon wafers.
3. Application of crystalline boron in semiconductor sputtering targets:
3N and 4N crystalline boron particles can be added to functional alloy products to form targets for semiconductor sputtering coating.
4. Applications of Crystalline Boron in Optics:
Crystalline boron also has extensive applications in optics. Due to its excellent nonlinear optical properties, crystalline boron can achieve functions such as light modulation, frequency sweeping, and frequency doubling. Therefore, crystalline boron is widely used in optical devices, including optical modulators, optical frequency combs, and lasers. Furthermore, crystalline boron can also be used as a gain medium in infrared lasers, exhibiting a large emission cutoff and a wide excitation spectrum range.
5. Crystalline Boron in High-Hardness Ceramic Materials:
結晶硼也可用於製備高硬度材料，例如碳化硼（B4C）和石墨硼化合物（Bg）。碳化硼是一種極硬的陶瓷材料，具有優異的耐磨性和耐高溫性，因此廣泛用於製造防彈裝甲、硬質工具、磨料和耐磨陶瓷。石墨硼化合物是具有石墨狀結構的材料，具有高導電性和熱穩定性，可用於製備高性能導電黏結劑、導熱材料和摩擦材料。
6. 晶體硼在熱電池中的應用：
熱電池是以熔鹽為電解質的單相熱激活儲能電池。它們具有體積小、重量輕、儲存時間長、免維護、啟動快速可靠、工作溫度範圍寬等優點，廣泛應用於一些戰略和常規武器的點火裝置中。熱電池的負極材料對其容量、體積和功率輸出起著決定性作用。熱電池負極材料經歷了從最初的鎂基和鈣基材料到目前鋰基材料的演變。例如，鋰硼複合材料具有能量密度高、功率輸出高、極化低、電化學電位接近純鋰、在600℃以上仍保持固態等突出優點，是最有發展前景的熱電池負極材料，並正逐步應用於高端熱電池。
7. 晶體硼在軍事工業的應用：
結晶硼可用於製造高純度硼陶瓷彈道材料、高純度硼延遲劑、高純度硼焊接助焊劑、高純度硼炸藥以及高純度硼富氧火箭推進劑。
