Fluorite, at the same time, fluorite is also a non-renewable resource, and is a national strategic mineral approved by The State Council.

If you do not know what fluorite is, then you must know luminous pearl, yes, luminous pearl is fluorite, because the main component of fluorite is calcium fluoride, Mohs hardness is only 4, a little weak, not suitable for making jewelry, so now most of the fluorite will not be used directly to do something, in addition to our own use, mainly exported to India, Japan, the Netherlands, the United States, etc. Most of it is used to produce hydrofluoric acid, which is a magical and versatile thing that is one of the most critical raw materials for the manufacture of various organic and inorganic fluorides

For example, the high-purity hydrofluoric acid market is basically all accounted for by Japan, of which Rising Chemical, Daikin, Morita Chemical three Japanese companies have a market share of more than 93% of the world, no problem of monopoly.

The high-purity hydrofluoric acid is one of the most critical auxiliary materials in the semiconductor industry, mainly used in semiconductor processing cleaning and etching, for example, the role of the lithography machine is to reduce the large circuit diagram and project it onto the silicon chip, and then the silicon chip is so small, with what to this
silicon
It is a photovoltaic, semiconductor industry widely used substrate material, more than 90% of the chips are currently made of silicon-based materials, manufacturing chips is like building a house layer by layer up repair, silicon chips for chips, equivalent to land, all transistors, wiring are completed on the silicon.
Hello, the raw materials of the chip include silicon, copper, aluminum, tin, gold, silver and so on. Among them, silicon is the most important raw material, the basic material used to make chips. Other materials such as copper, aluminum, tin, etc. are used to make wires and connectors for chips. Gold and silver are used to make the chip's contact points and circuit connections.
The raw material of a chip is a wafer.
The wafer is made of silicon, which is refined from quartz sand. The quartz sand is smelted into metal silicon, and then the polysilicon is heated and fused to make high-purity silicon rods, and then the silicon rods are cut into slices, and finally the steps of grinding, polishing, cleaning, etc. These slices are the wafers required for chip production.
Sand. Cell phone chips are made of silicon. The main raw material of the mobile phone chip is the wafer, and the raw material of the wafer is the silicon in the sand, so the chip of the mobile phone computer is mainly composed of silicon.
Silicon is refined from quartz sand, the silicon element is purified in the wafer, and then these pure silicon into silicon rods, which become the material for the manufacture of integrated circuits. Use a monocrystal silicon wafer as the base, then use lithography, doping, CMP and other technologies to make MOSFET or BJT components, and then use thin film and CMP technology to make wires, so that the chip is completed. Due to product performance requirements and cost considerations, wire can be divided into aluminum process and copper process
One of the raw materials that can produce chips is fluorite, which is a mineral that can emit light, is also a common mineral in nature, and it is also a non-renewable resource

Its main component is calcium fluoride, also known as fluorspar, it can be symbiotic with many kinds of minerals, many countries in the world have large and small fluorspar distribution
