Koalas were declared endangered in eastern Australia on Friday, with more and more koalas dying from disease, habitat loss, and other threats. Earlier, the koala was considered a vulnerable species, and the Commonwealth Department of the Environment changed its protection level to endangered on the east coast of Queensland, New South Wales, and the Australian Capital Territory. Many koalas in Australia are infected with chlamydia. The disease can cause blindness, infection, and infertility. Last year, the Australian Koala Foundation said Australia had lost about 30 percent of its koala population in the past three years. Without immediate action, the species could become extinct by 2050.
Unlike koalas, which are on the brink of extinction, the market demand for spherical quartz powder will grow substantially.
Quartz powder, also known as silica powder, is a hard, wear-resistant, stable chemical properties of silicate minerals, its main mineral composition is SiO2. The color of quartz powder is milky white, or colorless translucent. The hardness is 7. The density is 2.65. Slightly soluble in KOH solution. The melting point is 1650℃.
The product with the general fineness in 120 mesh below is called quartz sand, and that more than 120 mesh is known as quartz powder. Quartz powder can be divided into nanometer silicon dioxide and spherical silica powder because of its fineness and morphology.
Quartz powder is widely used in the industry, including the glass industry, machinery industry, artificial quartz stone plate, ceramics and metallurgy, construction, chemical industry and other industries used in the number of products in dozens to hundreds of mesh, purity requirements are different; In plastics, coatings, adhesives and other industries as fillers, fineness requirements in hundreds of mesh to thousands of mesh, high purity requirements; Used in the integrated circuit industry, product mesh and purity requirements.
Quartz powder can be used as filler to add plastic, rubber, coating, etc., to improve performance, improve process characteristics, reduce costs, etc.
The hardness of paint film can be improved by adding high purity quartz powder into the coating. High purity spherical quartz powder has special optical properties that conventional silicon dioxide does not have. It has strong UV absorption and red-light reflection characteristics. The spectrophotometer test shows that the absorption rate of ultraviolet light within the wavelength of 400mm is as high as 70%. It can be added to the coating to form a shielding effect, to achieve the purpose of UV aging and thermal aging, while increasing the heat insulation of the coating. The high purity quartz powder was added to the coating, which obviously weakened the radiation degree of UV light to the coating, and thus reduced the curing speed of the coating.
Quartz sand can be used to remove rust because of its high hardness.
The quartz sand is installed in the sand-blasting machine, through higher air pressure or water pressure, spewed quartz sand to the metal surface of the rust, through the quartz sand and rust surface of high-speed friction contact to achieve the effect of rust removal. Some manufacturers choose to use river sand instead of quartz sand because of its low cost. But the hardness of river sand is much lower than quartz sand, the content of silica in the two is different, quartz sand silicon content of nearly 99.9%, and the soil content of river sand is more, in the sandblasting process, river sand will be quickly broken or stand on the metal surface, cannot achieve the effect of real friction derusting, and the quartz sand for derusting. High hardness, uniform, and angular particles can be fully stable contact with the rusty surface, to achieve the effect of rust removal.
Quartz powder also has a filtering effect. Quartz powder is mainly used for water treatment to remove turbidity, soften water, and reverse osmosis pretreatment, can also be used for surface water and groundwater. It can effectively remove suspended matter, organic matter, colloid, and sediment in water.

Gas prices in European countries are expected to triple if Russian supplies are restricted, according to a press release from Rystad Energy, a Norwegian Energy consultancy.
The price of natural gas in Europe was $1,200 per 1,000 cubic meters on Tuesday. The benchmark price is already 300 percent higher than a year ago. European gas prices are expected to continue to soar to $3,500 per 1,000 cubic meters if Russian supplies are restricted, according to Analysis by Monitor.
In 2021, Russia delivered 155 billion cubic meters of gas to Europe, accounting for 31 percent of its gas supply, according to an analysis by Monitor Advisors. It would be difficult for Europe to replace Russian gas, which would also destabilize the global LNG market and have a profound impact on Europe's population and economy.
The analysis also said that if Russia stopped supplies now, Europe's current gas reserves would be exhausted by the end of the year, setting in for a cold winter.
In addition, affected by the geopolitical factors, the supply of the spherical quartz powder is erratic and thus its prices are expected to go higher in the future.
