Some mineral-like substances are noncrystalline, also described as amorphous, which means they have a random atomic structure. Natural volcanic glass, obsidian, is an example.

Submissions on chemical, electronic, optical and mechanical properties of glasses, amorphous semiconductors and metals, sol-gel materials, the liquid state of these solids and the …

In condensed matter physics and materials science, an amorphous solid (or non-crystalline solid) is a solid that lacks the long-range order that is a characteristic of a crystal.

非晶质（amorphous substance）又称“ 玻璃质 ”。 组成物质的原子或离子不呈规则排列，因而不具格子构造的固态物质，例如，玻璃、塑料，地质作用中由火山熔岩流快速冷凝而成的黑曜岩、 …

May 23, 2024 · The basic difference between crystalline and noncrystalline structures is their atomic arrangement. Crystalline structure has atoms arranged in order whereas noncrystalline …

非晶态材料也叫无定形或玻璃态材料，这是一大类刚性 固体，具有和晶态物质可相比较的高 硬度 和高 粘滞系数 （一般在10泊，即10帕·秒以上，是典型 流体 的粘滞系数的10倍）。 非晶态材 …

A non-crystalline object or substance is not a crystal (= a solid consisting of atoms or molecules that are arranged in a regular structure) or made of up crystals. In a non-crystalline material, …

Noncrystalline solids, also known as amorphous solids, lack the long-range order and regularity found in crystalline solids. Instead, their atomic or molecular arrangement is more random and …

We are going to focus on the 6 crystal systems: triclinic, monoclinic, orthorhombic, tetragonal, hexagonal, and cubic and how to describe the unit cell, the primitive lattice vectors, and …
