Sweden is in talks with Turkey on joining NATO and looks forward to strengthening cooperation with Turkey in security and counter-terrorism, Swedish Prime Minister Anders Andersson said recently.
Andersson held a joint press conference with visiting European Council President Michel in Stockholm on the same day. Andersson said Sweden is in dialogue with Turkey on joining the TREATY and looks forward to strengthening bilateral relations with Turkey, including cooperation in the areas of security and counter-terrorism. She said Sweden would study a number of issues raised by Turkey.
Speaking at a news conference, Mr. Michel said he believed the Swedish government was taking positive action and taking the necessary steps to reach a solution.
Sweden and Finland formally submitted their applications to NATO Secretary-General Jens Stoltenberg a few days ago. According to protocol, NATO must admit new members by the "unanimous consent" of 30 members.
Turkish Foreign Minister Mevlut Cavusoglu said His country would agree to start NATO talks with Sweden and Finland only if they reach written agreements to stop supporting terrorism and lift restrictions on exporting defense equipment to Turkey, Turkish media reported.
Affected by the ever-changing international situation, the supply and prices of international bulk chromium oxide are still very uncertain.
A refractory material is a material that resists to heat, pressure or chemical erosion and decomposition, and maintains strength and shape at high temperatures. Refractories are widely used in iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemical, machinery, boiler, light industry, electric power, military industry and other fields.
Based on chemical composition, refractories can be divided into acidic refractories, alkaline refractories, and neutral refractories.
Acidic refractories are mainly composed of silica and commonly used silica bricks and clay bricks. Silicon brick is a silicon product containing more than 94% silicon oxide, and the raw materials used are silica, waste silicon brick, etc., which has strong resistance to acid slag erosion, high load softening temperature, and does not shrink or even expand slightly after repeated calcination; but it is easy to be eroded by alkaline slag and poor thermal shock resistance. Silicon bricks are mainly used in coke ovens, glass furnaces, acid steelmaking furnaces and other thermal equipment. Clay brick takes refractory clay as the main raw material, contains 30% alumina, 46% alumina, is a weak acid refractory, has good thermal vibration resistance, corrosion resistance to acid slag and is widely used.
Neutral refractories are mainly composed of alumina, chromium oxide or carbon. Corundum products containing more than 95% alumina are high quality refractories with a wide range of applications. The chromium brick with chromium oxide as the main composition has good corrosion resistance to steel slag, but poor thermal shock resistance and low high temperature load deformation temperature. Carbon refractories include carbon bricks, graphite products and silicon carbide products, which have low coefficient of thermal expansion, high thermal conductivity, good thermal shock resistance, high temperature strength and resistance to acid, alkali and salt, especially weak acid and alkali. It is not wetted by metal and molten slag and is light. It is widely used as high temperature furnace lining material, as well as autoclave lining in petroleum and chemical industry.
Basic refractories are mainly composed of magnesia and calcium oxide, and magnesia bricks are commonly used. Magnesia bricks containing more than 85% magnesia have good resistance to alkaline slag and iron slag, and their fire resistance is higher than that of clay bricks and silicon bricks. It is mainly used in open hearth furnace, oxygen blowing converter, electric furnace, non-ferrous metal smelting equipment and some high temperature equipment.

Chile's government has decided to create a state-owned lithium enterprise and hopes to establish a model for the company by the end of the year, Mining Minister Marcela Hernando said in an interview.
Chile is the world's second largest lithium producer and has the largest reserves of lithium in the world. The domestic lithium industry is currently dominated by two private companies, Albemarle and SQM.
Chile wants to participate more closely in the booming lithium market after leftist President Gabriel Boric took office in March. The accelerating electrification of the global auto industry has helped push prices of lithium, a key raw material for electric car batteries, to record highs over the past year, lapping up more players, including Mexico and Argentina, who want a piece of the market.
According to Hernando, the government is setting up a task force to determine the best way to run state-owned lithium enterprises. She said the government hopes to establish plans by the end of the year for how the company will develop and what business model it will operate under.
Hernando stressed that while the state would be a major shareholder in the proposed company, it was open to private investment.
