It is black like pitch, dense, opaque, metallic luster. It is soft. Hardness 2.5. d 1.75~1.80, making graphite acid from concentrated nitric acid without melting in a fire zone.

Illite in the present invention has a chemical composition of (K,H ₃ O)Al ₂ (Si,Al) ₄ O ₁₀ (H ₂ O,OH) ₂ . In terms of chemical composition, some are close to muscovite mica, but relatively SiO ₂ , MgO, H ₂ O are high, and K ₂ O is low. It is a series of minerals such as hundreds of mica (水白雲母). Hardness 1 to 2, specific gravity 2.6 to 2.9. The cleavage is complete, and the streak color is white, and there is a earthy gloss. There is a view that it is not an independent mineral in terms of its chemical composition or crystal structure, but a mixed mineral containing other components. It is produced in aluminum-rich heterogeneous or tuff-like sedimentary rocks, and is produced as a metamorphic mineral of a hydrothermal mineral bedrock.

Zeolite in the present invention is also referred to as a tombstone. There are many types, but they have a lot in common, such as the point of having a lot of water content, the properties of crystals, and the acid phase. The hardness does not exceed 6, and the specific gravity is about 2.2. It is generally colorless, transparent or white translucent. When heated with a blowpipe, it boils and becomes bulging, so it got this name. Most types dissolve in hydrochloric acid and are often glued, but few types do not dissolve in hydrochloric acid. As the main types, there are Bangbistone, Fisheye Stone, Chabazite, Soda Stone, Heullandite, Steelbite, Lomontite, and Innessite. It is produced from voids or fissures of basic igneous rocks such as basalt or tuff, and sometimes exists as a secondary mineral among granite and gneiss. In addition, it may be produced in gold or other veins. In the crystal structure, the bonds of each atom are loose, and even if the moisture filling between them is released by high heat, the skeleton remains intact, so other particulate matter can be adsorbed. Using this property, it is used as an adsorbent, and it is used as a molecular sieve that separates fine particles of different sizes.

Elvan stone referred to in the present invention is known as a term used in Chinese herbal medicine, and belongs to granites when classified geologically. It is the same as quartz porphyry, feldspar porphyry, and granite porphyry, and the name of the rock coincides with quartz-monzonite. Quartz and feldspar are densely mixed. Yellowish white, light yellowish brown, light gray, dark green or light green rocks with red dots or white dots evenly mixed together are like rice balls made of barley, so the name Elvan Stone was given. The main components are silicic anhydride and aluminum oxide, and it contains a small amount of iron oxide. Known as the yellowish white elvan stone, it was used as an anti-inflammatory agent to treat skin diseases such as swelling or boils on the back and a filter to purify pills. According to Donguibogam, its nature is sweet, warm, and non-poisonous. It is composed of 30,000 to 150,000 holes per 1 cm ^3, so it has strong adsorption and contains about 25,000 kinds of inorganic salts.

It is light and soft enough to smear powder when you touch it with your fingers. Because it is a fine porous material, it has strong absorbency and is a poor conductor of heat. Diatomaceous earth in our country is calculated as soil within the tertiary or fourth stratum. During the third period of the ancient period of our country, fault movements in the northeast to northeast directions occurred, and earth-zone sedimentary basins were formed in several places. The Yeongil Basin, the Earth Zone between Gilju and Myeongcheon, the Earth Zone between Seoul and Wonsan, and the Tuman River Basin were formed, and the third base was deposited there. When sedimentary layers were formed, diatoms were deposited in small shallow lakes or freshwater basins in various places to form deposits. Among these sedimentary basins, diatomaceous earth in Yeongil Bay is the largest in diatomite deposits, and is found intensively in Wolseong and Yeongil, Gyeongsangbuk-do. In addition, in North Korea, Haenghyeon-ri, Munsan-myeon, Anbyeon-gun, Anbyeon-gun, Namsan-ri, Anbyeon-myeon, Anbyeon-gun, Hamgyeongbuk-do, Hoemun mine, Bupyeong-dong, Junam-myeon, Gyeongseong-gun, Gyeongseong-gun, Hoemun mine, Ungpyeong-myeon, Gilju-gun, Sanbon mine, Myeongcheon-gun, Myeongcheon-gun Seomyeon, Baekrok mine, Gangwon-do The production centers of Sephori, Gosaph-myeon, Pyeonggang-gun, and so on are known. The development of diatomaceous earth as a deposit in Korea began in 1941 when it was incorporated as a designated legal mineral under the'Chosun Mining Ordinance'. Since then, domestic diatomite deposits have been discovered in various places, and in particular, diatomaceous earth produced in Iil-ri, Yangbuk-myeon, Wolseong-gun, Gyeongsangbuk-do, is said to have been used as a raw material for the manufacture of Asahi furnaces in Japan at Nodong-ri, Gyeongju. In recent years, it is used as a refractory material, and because of its strong absorption, it is mostly used as a filter material for purification of industrial water, water, pharmaceuticals, and food. In addition, it is used as a filler for plastics and paper, adsorbent for dynamite, hemostatic agent, and a mixture of cement.
