Phosphine gas (PH3) is used in the electronics industry:

 PH3 is used in the diffusion process (Diffusion) doping for Silicon to create the N region in the PN transition region on semiconductor devices such as transistors, diodes, sensors, microprocessors and other electronic components.

Phosphine gas (PH3) can be used to sterilize and preserve agricultural products in warehouses:

Disinfection and preservation of rice, rice and grains: PH3 gas is used to kill harmful insects and pests in rice, rice and grain warehouses. The use of PH3 gas helps preserve agricultural products and prevent the growth of bacteria, mold and harmful insects.

Seed preservation: PH3 gas can also be used to preserve seeds in warehouses, helping to prevent the growth of harmful insects and preserve the quality of seeds.

Preserving other foods: In addition to paddy, rice and grains, PH3 gas can also be used to preserve other foods such as cashews, walnuts, and other foods in storage.
