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.
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 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.
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.
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.
