GaN crystals can be grown from a molten Na/Ga melt held under 100 atmospheres of pressure of N 2 at 750 °C. As Ga will not react with N 2 below 1000 °C, the powder must be made from something more reactive, usually in one of the following ways: 2 Ga + 2 NH 3 → 2 GaN + 3 H 2 [61] Ga 2 O 3 + 2 NH 3 → 2 GaN + 3 H 2 O [62]
The crystals are trigonal and chiral (space group 152 or 154 depending on the chirality), like the gray form of selenium. It is a brittle and easily pulverized metalloid. Amorphous tellurium is a black-brown powder prepared by precipitating it from a solution of tellurous acid or telluric acid (Te(OH) 6). [10]
Hemimorphite "spray" of crystals from Durango, Mexico (size: 2.9 × 2.1 × 2.0 cm). Hemimorphite most frequently occurs as the product of the oxidation of the upper parts of sphalerite bearing ore bodies, accompanied by other secondary minerals which form the so-called iron cap or gossan.
Mesophase. A mesogen is a compound that displays liquid crystal properties. [1] [2] Mesogens can be described as disordered solids or ordered liquids because they arise from a unique state of matter that exhibits both solid- and liquid-like properties called the liquid crystalline state. [1]
Liquid crystals used in dyes and inks often come microencapsulated, in the form of suspension. Liquid crystals are used in applications where the color change has to be accurately defined. They find applications in thermometers for room, refrigerator, aquarium, and medical use, and in indicators of level of propane in tanks.
The history of aperiodic crystals can be traced back to the early 20th century, when the science of X-ray crystallography was in its infancy. At that time, it was generally accepted that the ground state of matter was always an ideal crystal with three-dimensional space group symmetry, or lattice periodicity.
