1. Definition and composition of stone powder
Stone powder, as the name suggests, is a powder ground from natural ores. According to different ingredients, stone powder can be divided into many types. Common ones include calcium carbonate powder, talc powder, silica powder, etc. The following are several stone powders that have become popular recently and their uses:
| Type | Main ingredients | Main purpose | Popular discussion points |
|---|---|---|---|
| calcium carbonate powder | CaCO₃ | Building materials, food additives | food safety controversies |
| Talcum powder | Mg₃Si₄O₁₀(OH)₂ | Cosmetics, medicine | Potential cancer risk |
| Microsilica powder | SiO₂ | Electronic materials, coatings | High-tech application scenarios |
2. Controversies and hot spots about stone powder
In the past 10 days, discussions about stone powder have mainly focused on the following hot topics:
1.Food safety issues:The safety of calcium carbonate powder as a food additive (such as flour whitener) has caused widespread controversy. A well-known popular science blogger pointed out that excessive intake may lead to stones, but it is safe when used within the official standards.
2.Cosmetic safety:Talcum powder is restricted in many countries because it may contain asbestos impurities. An international brand paid a huge amount of compensation due to a talcum powder lawsuit, and the related topic has been read more than 5 million times.
3.Industrial application breakthroughs:The application of silica powder in the semiconductor field has become a hot topic in science and technology. A research team announced the preparation of a new energy storage material using silica powder, and the number of citations of related papers increased sharply.
3. Market data of stone powder
According to recent industry reports and statistics, the market performance of stone powder is as follows:
| Type | Global Market Size (2023) | annual growth rate | main producing countries |
|---|---|---|---|
| calcium carbonate powder | $22 billion | 5.2% | China, United States |
| Talcum powder | $2.8 billion | 3.8% | India, France |
| Microsilica powder | US$1.5 billion | 12.7% | Japan, Germany |
4. How to correctly understand stone powder
1.Distinguishing purposes:The standards of industrial grade and food grade stone powder are very different and cannot be mixed.
2.Pay attention to certification:When purchasing products containing stone powder, pay attention to FDA, ISO and other certification marks.
3.Scientific attitude:There is no need to panic too much, but you need to be wary of unscrupulous merchants abusing low-quality stone powder.
Recently, sampling data released by a testing agency showed that about 8.3% of calcium carbonate powder products on the market did not meet food-grade standards. This result has exacerbated public concerns. Experts suggest that supervision should be strengthened and consumers’ identification capabilities should be improved.
5. Forecast of future trends
With the advancement of technology, the stone powder industry is showing two major trends:
1.Refined development:Research on the application of nanoscale stone powder in the medical field has become increasingly popular, with the number of related patent publications increasing by 17% in the past 10 days.
2.Environmental transformation:Green mining and degradable stone powder have become new directions in the industry. A listed company announced an investment of 500 million to build a zero-emission production line, and its stock price hit the limit that day.
In summary, stone powder, as an important industrial raw material, has both its application value and potential risks. Consumers and practitioners should maintain rational understanding, not only make full use of its characteristics, but also prevent the harm caused by improper use.
