對于陶瓷、搪瓷釉料，氧化硼是很好的助熔劑和網絡形成體。它可形成玻璃（在低溫時），提高坯釉適應性，降低粘度和表面張力，提高折射率，提高機械強度，耐久性耐磨性，它是無鉛釉的重要組成。那么您知道硼酸在反應堆中的作用是什么嗎？下面氫氧化鉀廠家為您解答。

For ceramic and enamel glaze, boron oxide is a good flux and network formation. It can form glass (at low temperature), improve the adaptability of body glaze, reduce viscosity and surface tension, improve refractive index, improve mechanical strength, durability and wear resistance. It is an important component of lead-free glaze. Do you know the role of boric acid in reactor? The potassium hydroxide manufacturer will answer the question for you.

硼酸是一種大中子吸收截面的物質，在反應堆中主要是用來調節反應性用的，加入適量的硼酸可以降低反應性。天然硼元素有兩種穩定同位素,即B-10和B-11，豐度分別為1978%和8022%。

Boric acid is a material with large neutron absorption cross section, which is mainly used to adjust the reactivity in the reactor. Adding an appropriate amount of boric acid can reduce the reactivity. There are two stable isotopes of natural boron, namely B-10 and B-11, with the abundances of 1978% and 8022% respectively.

B-10具有對中子高吸收的獨特特性，B-10對熱中子的吸收截面為3837bar(1b=10，Pa)，自然豐度的硼的對熱中子的吸收截面接近于750bar，而B-11僅為0005bar，因此B-10對熱中子的吸收截面是自然豐度硼的5倍還多，是石墨的20多倍，是傳統防護材料混凝土的500多倍。

B-10 has a unique feature of high neutron absorption. The absorption cross section of B-10 for thermal neutrons is 3837bar (1b=10, Pa). The absorption cross section of natural abundance boron for thermal neutrons is close to 750bar, while B-11 is only 0005bar. Therefore, the absorption cross section of B-10 for thermal neutrons is more than 5 times of natural abundance boron, more than 20 times of graphite, and more than 500 times of traditional protective material concrete.

就是說，硼-10同位素是高的效的熱中子吸收劑。因此在核電站中它是和控制系統中所不可缺少的。

In other words, the boron - 10 isotope is a highly effective thermal neutron absorber. Therefore, it is indispensable in the safety and control system of nuclear power plants.

硼酸的用途有哪些？例如，在玻纖生產中經可降低熔融溫度從而有助于拉絲。一般來講，B2O3可以降低粘度、控制熱膨脹、阻止失透、提高化學穩定性、提高抗機械沖擊和熱沖擊能力。在要求鈉含量較低的玻璃生產中硼酸常常與鈉硼酸鹽（如五水硼砂或無水硼砂）混合使用以調節玻璃中的鈉硼比。

What are the uses of boric acid? For example, in the production of glass fiber, the melting temperature can be lowered to facilitate wire drawing. Generally speaking, B2O3 can reduce viscosity, control thermal expansion, prevent devitrification, improve chemical stability, and improve resistance to mechanical shock and thermal shock. In the production of glass requiring low sodium content, boric acid is often mixed with sodium borate (such as borax pentahydrate or anhydrous borax) to adjust the sodium boron ratio in glass.
