Europe's largest economy, Germany, recently activated an emergency plan to manage gas supplies that the natural gas could be rationed if supplies are disrupted or disrupted by a stand-off over Russian demands to pay for fuel in rubles.
German Vice-Chancellor, minister of economy and climate protection, said Germany's gas supplies were secure for now, but he urged consumers and businesses to reduce consumption, saying "every kilowatt of electricity counts."
Germany's gas network regulator can ration gas if supplies run short. Plants would be the first to be affected. Special treatment will be provided to private families, hospitals, and other important institutions.
Half of Germany's 41.5 million households use natural gas for heating, and industry consumption accounts for a third of the country's 100 billion cubic meters of gas demand in 2021.
The price of many energy and commodities like the silicon nitride could be affected.
What is silicon nitride?
Silicon nitride formula is Si3N4. Silicon nitride has two crystal forms: an and β. A-Si3N4 is granular crystal and p-Si3N4 is acicular crystal, both of which belong to hexagonal system.
Silicon nitride relative density is 3.18. Silicon nitride Morse hardness scale is 9. Low coefficient of thermal expansion, good chemical stability and excellent oxidation resistance. It decomposes into nitrogen and silicon at 1900℃. The strength of silicon nitride is very high and resistant to high temperature. Even if the high temperature is 1200℃, its strength will not change, it will not melt when heated. And it will not decompose until 1900℃. It has strong chemical corrosion resistance and can withstand the corrosion of almost all inorganic acids and a variety of organic acids. Silicon nitride has the advantages of hardness, low coefficient of thermal expansion, excellent thermal shock stability, good insulation, stable chemical properties and high mechanical strength.
Silicon nitride properties

Good oxidation resistance.
Good chemical corrosion resistance.
What are the advantages of silicon nitride?
Compared with other technical ceramics, the low thermal expansion coefficient of silicon nitride provides good thermal shock resistance. It is very hard, better than most metals in terms of high temperature capacity, and has excellent oxidation resistance. As a result, silicon nitride can withstand the harshest conditions in the most demanding high temperature and high load applications.
When the silicon nitride bearing is used in the main engine of the space shuttle, it is identified as one of the few integral ceramic materials that can withstand severe thermal shocks and thermal gradients produced by hydrogen / oxygen rocket engines, and proved to be completely reliable throughout the space shuttle program.
What is silicon nitride used for?
Used for insulating materials, mechanical wear-resistant materials, heat engine materials, cutting tools, advanced refractories and corrosion-resistant, wear-resistant sealing parts, etc.
Silicon nitride ceramics can be used as combustion chamber of gas turbine, mechanical sealing ring, pipeline and valve of electromagnetic pump for conveying liquid aluminum, permanent mold, molten steel separation ring and so on.
Silicon nitride has a small friction coefficient and is used in high temperature bearings. its working temperature can reach 1200 ℃, which is 2.5 times higher than that of ordinary alloy bearings, and its working speed is 10 times that of ordinary bearings.
The use of silicon nitride ceramic with good electrical insulation and rapid cold and heat resistance can be used as an electric plug, which can greatly shorten the engine starting time and start the car quickly in cold weather.
Silicon nitride ceramics also have good microwave permeability, dielectric properties and high temperature strength, which can be used as radar radome for missiles and aircraft.

The drought in Europe is still getting worse. The drought in France is particularly severe. Recently, the French Prime Minister's Office issued a statement saying that the current drought in France is the worst in history. Prime Minister Borne decided to activate an inter-ministerial crisis group to deal with the drought. French Minister for Ecological Transformation Christopher Beshu said that there is no drinking water in pipes in more than 100 towns across France. In addition, Italy also suffered from hot and dry weather, with the highest temperature exceeding 40 ℃ on the 5th local time, and several cities, including the capital Rome, issued a red alert for high temperatures. The country is experiencing its worst drought in more than 220 years.
British officials have released statistics on the sequelae of COVID-19, which has aroused concern. As of July 2, 1.8 million people in the UK were suffering from the symptoms of "long COVID-19", according to a report released by the Office for National Statistics. Among them, 14% of the people were not cured within 12 weeks, and 81% of the people were infected for more than 12 months.
