White oyster is a common shell with a brilliant luster on its surface, like a layer of pearls. White mother-of-pearl is not only a beautiful ornament, but also a useful material, which is widely used in crafts, jewelry, musical instruments, architecture, and other fields. So, what is the white mother-of-pearl material?How did it come to be, and what are its properties and uses?This article will unravel the mysteries of white oysters.
White oyster is a speciesOrganic-inorganic composites, which is made up of two main components:OrganicswithInorganics。Organic matter refers to the inside of the shellProteins, they mainly playBondingto connect inorganics together. Inorganic matter refers to the inside of the shellCalcium carbonate, they mainly playSupportrole, providing the hardness and strength of the shell. Calcium carbonate has two crystal forms:Calcitewitharagonite, they differ in structure and nature. Calcite is oneCubesIt has a lower refractive index, higher transparency, and a smooth surface. aragonite is one of a kindRhombusIt has a higher refractive index, lower transparency, and a rough surface. The outer layer of the white oyster is mainly composed of aragonite, while the inner layer is mainly composed of calcite. This hierarchy allows the white oyster to have:Excellent optical properties, which is able to reflect a variety of lights.
White oyster is a speciesMolluscsThe shell of which it is made of animalsMantlesecreted out. Mantle is a membrane that covers the surface of an animal's body, which is able to absorb from seawaterCalcium ionswithCarbonate ionsand combine them into crystals of calcium carbonate. At the same time, the mantle is also capable of secreting a method calledNacre proteinsIt is able to bond the crystals of calcium carbonate together to form the layered structure of the shell. The formation of white oysters is oneOngoing processAs the animal grows, the mantle expands outward, secreting a new layer of shells. In this way, the white oyster is able to adapt to the changes in the size of the animal and protect the safety of the animal.
White oyster is a speciesFunctional materials, which has the following characteristics and uses:
Aesthetics: The surface of the white mother's pearl is rich in color and luster, and it can show different hues and brightness depending on the angle and intensity of the light. This aesthetic has made white mother-of-pearl a popular decorative material that is used to make a variety of crafts, jewelry, musical instruments, and more.
Durability: The structure of the white oyster hasHigh degree of stabilitywithImpact resistanceIt is able to resist the physical and chemical attack of the outside world, maintaining its shape and color. This durability makes white mother-of-pearl a material suitable for long-term use, and is used to make a variety of buildings, furniture, tableware, etc.
Biocompatible: The composition and structure of the white oyster with that of the human bodyboneswithTeethThere are similarities in that it is able to relate to the tissues and cells of the human bodyWell combined, which does not cause rejection or allergic reactions. This biocompatibility makes white mother-of-pearl a promising medical material that is used in the manufacture of a variety of productsArtificial boneArtificial teethArtificial jointsWait.
White oyster is an organic-inorganic composite material composed of protein and calcium carbonate, which has excellent optical properties and is a beautiful ornament. White oyster is the shell of a mollusk secreted by the mantle, which is highly stable and impact-resistant, and is a durable material. White oysters share similarities with human bones and teeth, have good biocompatibility, and are a promising medical material. White mother-of-pearl is a functional material, and its formation, characteristics and uses are worth exploring and appreciating.
