    what is the production method of manganese dioxide powder

    Manganese dioxide, also known as "manganese peroxide", "black manganese oxide", is a black orthorhombic crystal or brown-black powder, and there are many variants. Insoluble in water, nitric acid, cold sulfuric acid and acetic acid, soluble in cold and concentrated hydrochloric acid to generate unstable light brown-green MnCl4, which is heated and reacted with concentrated hydrochloric acid to rel...

    What are the matters needing attention in the packaging, storage and transportation of nano powder

    1. Packaging of nano powders Most nanopowders will agglomerate again due to extrusion or moisture absorption, so the packaging of nanomaterials is very important. We will choose packaging materials according to the type, character and quantity of products purchased by customers, usually vacuum packaging in aluminum bags, or storage in water, we will tailor a reliable packaging solution for your go...

    Characterization of Nanopowders---Determination of Specific Surface Area

    The specific surface area is the surface area (㎡/g) of the substance per unit mass. It is one of the most important physical properties of ultra-fine powder materials, especially nano-powder materials. It is used to evaluate their activity, adsorption, catalysis and other properties. important physical properties. Therefore, in the research, manufacture and application of various ultrafine powder ...

    Nano ATO Antimony Tin Oxide powder can be used in thermal insulation materials

    In building energy conservation, the light transmission and heat insulation of glass is a very critical issue. In buildings with transparent ceilings and large-area exterior windows, the thermal radiation of sunlight will lead to an increase in the energy consumption of air conditioners, resulting in a large energy waste. In order to improve this phenomenon, nano-scale antimony doped tin oxide ATO...

    The difference between Fisher particle size and laser particle size, and share the sample dispersion method in particle size test

    Fisher's method is a relatively simple particle size measurement method, which is based on measuring the speed of air passing through the powder accumulation, and then obtaining the average particle size of the powder according to the Kozeny-Carman formula. However, the Fisher method is a relative measurement method, which cannot accurately determine the true particle size of the powder, and is on...

    Borax-ammonium chloride method is a commonly used method for synthesizing boron nitride

    This is a method of synthesizing boron nitride by reacting borax and ammonium chloride as the main raw materials in an ammonia atmosphere. The two raw materials should be dehydrated and recrystallized separately before participating in the reaction. Borax is best dehydrated in a vacuum at 200~400°C. The recrystallization of ammonium chloride is to dissolve it into a saturated solution, filter to r...

    The boron anhydride method is a commonly used method for the synthesis of boron nitride

    The synthesis of boron nitride by nitridation with boron anhydride (B4O3) is one of the important methods for industrial production of boron nitride. Due to the low melting point of boron anhydride (glass state is 294°C, crystalline state is 450-600°C), it becomes a high-viscosity melt at the nitriding temperature, which hinders the flow of ammonia and makes the reaction slow and extremely incompl...

    How to prepare and test the thermal insulation and infrared blocking properties of cesium tungsten oxide nanoparticles modified PVC film

    In summer, the sun is strong, and the sunlight enters the room through the glass, causing the temperature in the car to rise sharply, which seriously affects the comfort of living and vehicle riding. Among them, the energy in the infrared band accounts for the largest proportion, and it is also the main source of energy for the temperature increase in the place where the sunlight is irradiated. By...

    Comparison of thermal insulation test between cesium-doped tungsten oxide CSxWO3 glass and ordinary glass

    Infrared light has an obvious thermal effect, which can easily lead to an increase in ambient temperature. Ordinary architectural glass has no thermal insulation effect, and can only be achieved by means of filming. Therefore, architectural glass, car film, outdoor facilities and other surfaces need to use thermal insulation materials to achieve the effect of thermal insulation and energy saving. ...
