Into the famous Enterprise-Sasol not all pseudo-thin hydrobauxite is called "SB" powder

In the petrochemical industry, with the trend of heavier and poorer crude oil quality, blending heavy oil and residual oil into the feedstock for catalytic cracking has become a commonly adopted processing method. It necessitates the enhancement of the cracking capacity of fluid catalytic cracking (FCC) catalysts towards large molecular compounds, thereby requiring the catalyst supports to possess a high pore volume, which facilitates the diffusion of large molecular compounds into the interior of the catalyst particles, and a large specific surface area, which is conducive to the dispersion of active metals. Pseudo-boehmite (AlOOH·nH2O, n=0.08-0.62), as a precursor of catalyst supports, its crystallinity, particle size, aggregation state, and morphology significantly impact or even determine the performance of the supports.

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．

Why is magnesium oxide getting more and more popular? Hear what senior researchers have to say

Magnesium oxide (MgO) is a white fine ceramic powder, in addition to self-sintering to make MgO ceramics, can also be synthesized, compounded with other compounds or used as additives to make high-performance ceramics or crystals. Typical application scenarios for MgO are as follows

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.
