Does anyone know what Flintstone 20 is

It is a man-made alloy containing two special metals, cerium and lanthanum. When thorium is extracted from monazite (cerium lanthanum phosphate), cerium and lanthanum can be obtained from the by-products. Both of these metals are susceptible to oxidation in the air, so they are usually soaked in kerosene (commonly known as stinky oil) for preservation.

Cerium will oxidize rapidly and spontaneously ignite when heated, and lanthanum will be knocked or filed at room temperature, and the debris will quickly oxidize and spark. The fiery temperament of these two brothers is just a good use for people to make good use of it and become an excellent flint material. These two metals are silver-gray and silvery-white, and flint and steel usually look golden yellow, why is that?

It turns out that these two metals are not wear-resistant, and some copper or iron must be added to increase the hardness, so as not to grind out after hitting it a few times! Both of these metals belong to rare earth metals, of course, there are many uses, in the metallurgical industry, glass industry, petroleum industry, optical instruments, etc., there are other elements that cannot replace the importance.

Make flint! I used to use it on lighters! The kind that rubs the flint with a wheel to create a spark!

It is flint, if the stone you are talking about is a transparent crystal, it may be a thing called Xianxiu stone on the Yunnan-Guizhou Plateau, and the main component is a crystal of sulfate double salt! Collisions with each other create sparks.

That's not flint and steel, what color are you talking about? Is it white? We call it White Flint here, and we used to use this to live, and we also needed an auxiliary tool called "lighter".

Flint is saltpeter, which contains a lot of nitrate, and when it is hit or rubbed, it will produce a lot of heat and ignite.

What kind of stone is struck with an iron tool and there is no spark.

The chemical composition of flint and steel has a lot to do with the structure of flint, fire performance, etc.

Chemical composition. 1) Rare earth metal rare earth elements are the matrix in flint and steel alloys, which are the main components, and they have a large affinity for oxygen and release a lot of heat when reacting.

2) Iron element iron is the main filler in the alloy, which can improve the hardness of the alloy, and react with rare earth cerium to generate: and other intermetallic compounds, when the Fe content is less than 12%, the processing performance is good, and the ignition performance is poor, but when the Fe content is higher than 25%, the hardness is high, the extrusion force is large, and the forming is poor.

3) Magnesium element magnesium can form CEMG intermediate compounds with rare earth cerium, the ignition point is very low, the ignition performance is enhanced, the magnesium content is higher than 5%, and the ignition performance is good, but the extrusion forming pressure is high; If the magnesium content is too low, the luminescence performance is poor, and the grain refinement in the alloy makes the alloy tough, and it cannot be pulverized when rubbing, and the fire is not a spark but a flame.

4) Zinc element Zinc in the alloy does not help to ignite, but can increase the density and anti-corrosion performance of the alloy, therefore, the composition of zinc should not be high.

Flint is commonly known as "flint" and is mainly composed of cryptocrystalline quartz; It is a relatively common siliceous rock, dense, hard, mostly gray and black, with a shell-like fracture after being broken, flint because of its hardness, a sharp fracture after breaking, so it is the earliest favored by primitive people in the Stone Age, most of the stone tools are made of flint strikes, flint and iron tools will produce sparks, so it is also used as a fire tool for ancient people. It can be found deep in the mountains and old forests.

It can be found on the riverside where there are usually stones, but it has to be a sandy area on the bank of the river with pebbles, and there are some natural flints in the middle, which is a kind of earthy yellow translucent stone.

I have a lot of them here, as many as I want. It can be used as a raw material for carving. I'll pick up two random pieces on the side of the road and show them. Good flint is very beautiful and resembles agate.

It's the white kind of stone, look for it on the road

Flint and steel is a man-made alloy in which cerium is the main component. In addition, it also contains light rare earth elements such as lanthanum, praseodymium, and neodymium. The chemical properties of flint and steel rare earth metals are active, and the affinity for oxygen is strong, while the temperature of the ignition point of the cerium group metal is very low, and a lot of heat will be released by friction.

The main component of flint and steel is a cerium-iron alloy made of cerium and lanthanum before annihilation. The flint is usually used on a lighter, and the principle of ignition is that cerium and lanthanum are both easily flammable metals, and sparks will occur when rubbed or impacted.

3. Hand in hand with flint and wood bundles.

4. Throw the bundles of flint and steel onto the ground.

5. Select metal**.

6. Ignite the noise to attack the flint and firewood bundles, and you can use the flint to light a bonfire.

The explanation of the word flint is: refers to a natural flint that can spark after being hit by a lighter.

The explanation of the word flint is: refers to a natural flint that can spark after being hit by a lighter. Pinyin is: dǎhuǒshí. The pronunciation is: The structure is: hit (left and right structure) fire (single structure) stone (semi-enclosed structure).

2. Chinese dictionary.

A fire-making tool. A stone that can be used to make a fire by rubbing it to generate heat. It is characterized by high flammability and hard texture.

Such as flint, quartz, obsidian, light stone, etc. Translation of words English: Flint German feuerstein (zündsteininfeuerzeugen) (s, tech), feuerstein, flint(einmineral) (s, geol), familiefeuerstein(, us-amerikanischezeichentrickserie) (eig, kunst).

3. Network Explanation.

Flint and steel (chemical) flint and steel is a man-made alloy containing two special metals, cerium (CE) and lanthanum (LA). When thorium is extracted from monazite (cerium lanthanum phosphate), cerium envy and lanthanum can be obtained from the by-products. Both of these metals are susceptible to oxidation in dust or air, so they should be immersed in kerosene (commonly known as stinky oil) for preservation.

Idioms about flint and steel.

<> first need to prepare flint and flint and ignition materials. The second is to use a knife to scrape the magnesium powder directly to use it as a firestarter. Then use magnesium powder to make a fire, when making a fire, you must pay attention to preparing enough dry firewood for backup, and the poor cover will stare off the magnesium powder directly and the virtual and combustible materials together, and finally directly put the flint and steel against the ignition and rub it with metal, so that you can make a fire.
