Japan issued a new can reduce the dosage of rare earth fluorescent materials
Two years ago, Japan's relations with China, China offer a means of restrictions on rare earth exports to Japan, Japan was through, because the rare earth is widely used in various types of electronic products, less rare earths for manufacturing electronic products have considerable impact.
Because just can't wait to repair relations with China, Japan to without restraint, actively look for rare earth resources in other areas in Japan, and South Africa to develop rare earth resources. In addition, in Japan to the east of the south island, it is said that the bottom is a high concentration of rare earth deposit, filled with technology confident Japan ocean development company, think that using the exploitation of ocean oil field technology to develop rare earth resources under the sea is very possible.
Japanese companies are also reducing development of rare earth products technology. Panasonic recently published a new phosphor materials used in the LCD back light, the new material the use of rare earth quantity is less than one over ten of the past.
Because of China's rare earth export restrictions, the rare earth price is not as cheap as ever, reduce the use amount of rare earth, also equal to reduce the cost of products, raw materials will be used. Panasonic's new phosphor materials is therefore on cost was reduced by more than half, the reduce of the rare earth cerium (cerium) and europium (europium) concentration below 5%, with strontium (strontium) and silicone (silicone) concluded that the mix material, as a new fluorescent material for LCD backlight, performance, and also can do the light-emitting diode LED fluorescent body.
Japan's economy reported news lead, the past phosphor used the high proportion of rare earth materials, up to three to fifty percent. In addition according to the survey of the Japanese association of rare earth metals demand investigation, domestic need 5200 tons a year of cerium, accounts for forty percent of all rare earth. Currently used Japan is eighty percent rare earths from China, supply and price stability are existing variable, so the Japanese companies are trying to want to get rid of the dependence on Chinese rare earths.
