Xiamen Tungsten Co., Ltd. and China Rare Earth Group in-depth cooperation.

Xiamen Tungsten Co., Ltd. and China Rare Earth Group in-depth cooperation.

On the evening of September 24, XTC announced that the company signed a "Cooperation framework agreement" with China Rare Earth Group and planned to establish two joint ventures. Among them, China Rare Earth Group holds 51%, and XTC or its holding subsidiaries hold 49%. The joint venture will jointly operate rare earth mines and rare earth smelting and separation industries controlled by XTC (including its controlling shareholders and its controlling subsidiaries). The two sides strive to ensure that the recoverable rare earth oxide (REO) reserves in Fujian Province remain above 200,000 tons in the long term. In addition, within 2-3 years after the cooperation, the joint venture company also plans to invest in a new 5,000-10,000 tons of separation capacity in Fujian Province. XTC said that the signing of the agreement is conducive to accelerating the strategic coordination between the central and local areas and jointly promoting the high-quality development of the rare earth industry.

Effect of Content and Particle Size of MgO on Liquid-phase Sintering Behavior and Mechanical Properties of Si3 N4 -Y2 O3 -MgO Ceramics

Effect of Content and Particle Size of MgO on Liquid-phase Sintering Behavior and Mechanical Properties of Si3 N4 -Y2 O3 -MgO Ceramics

Abstract: The effects of MgO content and particle size on the density，phase composition，microstructure and mechanical properties of Si3 N4 -Y2 O3 -MgO liquid phase sintering system were investigated systematically in the present work． Ｒesults show that the effect of liquid phase could be more important due to the increase of MgO content，thus resulting in enhancing the final density of material and promoting the coarsening growth of β-Si3N4 grains． When the liquid phase content was the same but MgO particle size increased，the final density and aspect ratio of β-Si3N4 grains simultaneously tended to diminish． It is found that the MgO particle size has significant influence on the formation and distribution of liquid phase，hence affects the wettability，particle rearrangement and mass transfer during liquid phase sintering process． The relative density，fracture toughness and Vickers hardness reached maximum values of 99． 5% ± 0． 2% ，( 6． 9 ± 0． 6 ) MPa· m1 /2 and ( 18． 7 ± 0． 1 ) GPa，respectively at a MgO adding level of 4wt% and a particle size of 0． 1 μm．

Rare Earth Office Held Talks With Key Enterprises on Rare Earth Product Prices

Rare Earth Office Held Talks With Key Enterprises on Rare Earth Product Prices

As the market prices of rare earth products continue to rising and remaining stubbornly high, the Rare Earth Office held talks with China Rare Earth Group, North Rare Earth Group, Shenghe Resources Company and other key rare earth enterprises on March 3. The meeting called on relevant enterprises to strengthen their awareness of the overall situation and sense of responsibility, correctly grasp the relationship between the current and long-term, upstream and downstream, and ensure the safety and stability of the industrial chain and supply chain. Industry self-discipline should be strengthened to further regulate enterprises' activities such as production and operation, product trading and trade circulation, and refrain from engaging in market speculation and hoarding for profit. We should give full play to the role of demonstration and leadership, improve the pricing mechanism for rare earth products, and jointly guide product prices to return to rationality to promote the sustainable and healthy development of the rare earth industry.
