What is DEUTERIUM OXIDE CAS#7789-20-0?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is DEUTERIUM OXIDE which has developed particularly rapidly in recent years. Do you know about DEUTERIUM OXIDE ?
- The official answer:
- Heavy water (Deuterium oxide) is a compound composed of deuterium and oxygen, also known as deuterium oxide, molecular formula D2O, the relative molecular mass of 20.0275, about 11% higher than the relative molecular mass of water (H2O) 18.0153, so it is called heavy water.
- Due to the extremely small difference in the properties of deuterium and hydrogen, the chemical properties of heavy water and ordinary water are also similar, and the ion product constant of heavy water is 1.6 *10-15.
- In natural water, the content of heavy water accounts for about 0.02%.
- The electrolysis rate of heavy water is smaller than that of ordinary water, and it can be extracted by electrolysis.
- Heavy water has a certain difference from the boiling point of ordinary water, so it can also be purified by distillation.
What’s the application of DEUTERIUM OXIDE CAS#7789-20-0?
- The main use of heavy water is to be a “moderator” in nuclear reactors, reducing neutron velocity, controlling the nuclear fission process, and also a coolant.
- Heavy water and deuterium are a valuable tracing material in the study of chemical and physiological changes, for example, irrigating trees with thin heavy water, and it can be measured that water can run more than ten meters to tens of meters per hour in these plants.
- The deuterium content in the urine of people who have drunk a lot of dilute heavy water is measured, and it is known that the time of stay of water molecules in the human body is an average of 14 days.
- Replacing ordinary hydrogen with deuterium can study the digestion and metabolic processes of animals and plants. Concentrated or pure heavy water cannot sustain animal and plant life, and the lethal concentration of heavy water on general animals and plants is 60%.
- The special value of heavy water is reflected in the application of atomic energy technology, and to manufacture powerful nuclear weapons, heavy water is needed as a moderator in the fission reaction of atomic nuclei.
- Heavy water for nuclear power plants
Heavy water can be used as a solvent when using MRI analysis if the solvent is water and the object of study is hydrogen. - Neutron moderators: Some nuclear reactors use heavy water to slow down neutrons, giving them the opportunity to react with uranium.
- Light water can also be used as a moderator, but because light water absorbs neutrons, light water reactors must use enriched uranium, not ordinary uranium, otherwise they will not reach critical mass.
- Heavy water reactors not only can use ordinary uranium, but will also convert uranium-238 into plutonium that can be used to make nuclear bombs. India, Pakistan, Israel, and North Korea all use this method to produce nuclear fuel.
- In order to prevent the proliferation of nuclear weapons, the production and sale of heavy water is restricted in many countries.Heavy water has very important uses in cutting-edge technology.
- The heart of the atomic power station is the atomic reactor, and in order to control the normal progress of the nuclear fission reaction in the atomic reactor, heavy water is needed as a neutron moderator.
- Heavy hydrogen can be obtained by electrolyzing heavy water, which is the raw material for making hydrogen bombs, and China has successfully exploded the first hydrogen bomb on June 17, 1967, increasing the morale of Chinese people.
- More importantly, when heavy hydrogen undergoes nuclear fusion reactions, it can release huge amounts of energy and will not pollute the environment.
- Some calculations speculate that if the heavy hydrogen in seawater is used for thermonuclear reaction to generate electricity, its total energy is equivalent to the entire ocean being turned into oil.

WHY THEY SAY TO US
Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.
In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!
Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
Sincere Chemical team visited our USA factory in the year of 2017. We think highly of cooperation with them. We thanked you for the past excellent orders and best product quality.

I have visited Sincere Chemical company in the year 2018. Their company can be considered as one of the most professional, customer-focused, and product quality-driven companies that I have worked with in recent years.
We are a pharmaceutical products manufacturer in Brazil. I’m happy to cooperate with Sincere Chemical especially cooperate with Peter. Peter is patient and friendly. I’m satisfied with his 24*7 hours service. We are not only cooperators but also best friends with each other.
Great service and very supportive. This is my first order and I feel fortunate to be with Peter and his company. Product received was the right good quality product, so my review is more related with the quality, service and shipment. Thank you for sending. next time I will order again. Good supplier...
