Iron oxide red nano powder for sensitive materials:

1. Ultrafine Fe2O3 has semiconductor properties, and its conductivity is sensitive to temperature, humidity, and gas, and is a potentially sensitive material.
2. The gas sensor uses metal oxide to change the composition of the gas in the surrounding atmosphere to detect and quantify the gas by changing its electrical properties (such as resistance). The particle size used for gas sensors is one to several microns. The smaller the particle size, the larger the specific surface area. The greater the interaction between the surface and the surrounding contact surface, the higher the sensitivity.
3. It is found through experiments that α-Fe2O3 ultrafine powder has good sensitivity.
4. A gas sensor made of Fe2O3 prepared by the precipitation method has been tested and found that the conductivity of pure α-Fe2O3 is very small, and its sensitivity to CO with a mass fraction of 0.5% is low. By incorporating appropriate noble metals, carbonates and oxides, the conductivity and sensitivity can be significantly improved.

Application of Ferric Oxide Alpha Nanopowder:

1. Catalyst
2. Anti-rust additives.
3. Semiconductor materials.
4. Polishing agent, suitable for glass, gems and metals.
5. Pigments. Used in ink, paint and rubber, etc.
6. Gas purification to remove hydrogen and carbon monoxide.

Alpha Fe2O3 is corundum with stable physical properties. The mechanism of gas sensitivity is surface control.

As a main solid gas sensitive material, nano metal oxide semiconductor gas sensor has the advantages of high sensitivity, low manufacturing cost, and simple signal measurement. It is widely used in industrial production, environmental monitoring, medical care and other fields.
