Rare earth market quotation in China: terbium oxide, erbium oxide and holmium oxide prices continue to decline on April 19, 2023 mainly due to weak demand from downstream users and a strong sentiment to suppress prices. However, under this situation, good news has been continuously released, so the rare earth market is still expected to pick up.

In order to reduce the loss of W and extend its service life in high temperature oxidation environment. The development of self-passivating tungsten alloys and their surface protection technology has attracted widespread attention. Researchers investigated the performance of tungsten armor PFC at HHF to evaluate the choice of starting ITER operation with an all-tungsten shunt at heat currents of 10 and 20 MW.m^-2. The tungsten armor was subjected to 100-5000 cycles of thermal fatigue tests, and in the FE200 test, the change in surface morphology was not significant at a heat flow of 10 MW.m^-2 for 5000 cycles.

Molybdenum market quotation in China: sodium molybdate, ammonium molybdate and ammonium heptamolvbdate prices continue to decline on April 19, 2023. The enthusiasm of downstream users to enter the market for inquiries and purchases and the awareness of suppliers to insist on quotations have all increased, so the actual production volume is still acceptable.

Tungsten is widely used in nuclear fusion reactors as a highly regarded plasma-oriented material (PFM). However, it has poor oxidation resistance at high temperatures. In the event of a reactor de-cooling accident, the tungsten alloy is rapidly oxidized and volatilized as air enters the vacuum chamber, which will cause a catastrophic nuclear leakage accident. Scholars have conducted a lot of research and pointed out that the development of self-passivating tungsten alloys and surface protection technology is an effective way to solve this problem.
