在600~900℃温度范围内，研究了Be与Li2SiO3、Li4SiO4和不锈钢(AISI316)的化学兼容性，最大退火时间为1000h。Be Li 2 SiO 3和Be Li 4 SiO 4体系在6 5 0℃时首先发生化学作用，Be与Li 2 SiO 3的配伍性在6 5 0℃时似乎是足够的，而Be与Li 4 SiO 4的配伍性在70 0℃甚至是足够的。在600℃时，Be与不锈钢发生局部相互作用。因此，在等温条件下，Be/Li-硅酸盐/不锈钢体系中的相容行为由Be/钢的相互作用决定。
The chemical compatibility of Be with Li 2 SiO 3, Li 4 SiO 4 and stainless steel (AISI 316) was investigated in the temperature range between 600 and 900° C with maximum annealing times of 1000 h. Beryllium is of interest as a neutron multiplier material in a fusion reactor. First chemical interactions in the Be Li 2 SiO 3, and Be Li 4 SiO 4 systems occur at 650° C. The compatibility of Be with Li 2 SiO 3 seems to be sufficient up to 650° C, whereas that with Li 4 SiO 4 is sufficient even up to 700° C. At higher temperatures the silicide reaction products Li x Si y, become liquid which results in a strong local attack and penetration into the lithium silicates. Be interacts with stainless steel locally already at 600° C. The compatibility behavior in the Be/Li-silicate/stainless steel system under isothermal conditions is therefore determined by the Be/steel interactions.
