The meaning of silicon

Explanation of silicon: Silicon is a nonmetallic element and a semiconductor material, which can be used to make semiconductor devices and integrated circuits. Formerly known as "silicon". ?

Silicon words and sentences:

1, diatomite sentence: Seven kinds of clay powders: silicomagnesite, halloysite powder, bentonite, diatomite, kaolin, talcum powder and rice husk ash are soaked in three kinds of grain storage protectants: malathion, cartap and acarbose phosphate solution.

Description: Rock composed of diatoms and animal shells is light gray or yellowish white, porous and light. Industrially used as filtering, bonding, heat insulation materials, etc.

2. Silicon steel sheet sentence: In view of this situation, this paper puts forward an experimental method to measure the characteristic curve of silicon steel sheet at different frequencies for reference in the design of variable frequency motor.

Description: Also called silicon steel sheet. Silicon steel with silicon content 1.0 ~ 4.5% is generally rolled into thin plates. Hysteresis loss and eddy current loss are very small, so they are often used as magnetic materials in motors, transformers, electrical appliances and electrical instruments.

3.SCR in a word: most 800 kV DC devices, such as SCR valves and DC filter capacitors, can reach the level of 800 kV through appropriate improvement, and only need to develop converter transformers and wall bushings.

Description: A high-power semiconductor rectifier device. In addition to unidirectional conduction rectification, it can also control the current switch. Silicon controlled rectifier can also be used to convert DC into AC or change the frequency of AC. Widely used in electromechanical, chemical, metallurgical, transportation and automation technical fields.

4. Diatom sentence: MichaelStringer is a retired ophthalmologist from the seaside of ratcliffe, England. He won the first prize in the 2008 Nikon Microphotography Competition by taking photos of diatoms with a magnification of 200 times.

Description: A large class of algae plants, which grow in rising water or fresh water, are unicellular plants. The cell wall contains silicic acid, and the cells contain chlorophyll and brown pigment. Ancient diatoms deposited on the bottom of the water, forming diatom beds and oil.

5. Silicone rubber sentence: FOXY detector adopts optional silicone rubber protective coating (standard and medical grade) to exclude ambient light, improve chemical resistance and eliminate the influence of refractive index.

Description: A synthetic rubber. The raw material is dimethyldichlorosilane. It can resist high temperature and low temperature, and is mainly used to make seals, films and hoses for airplanes and spaceships, and also used as electrical insulation materials.
