[Chemical composition] contains trace amounts of Na, Ca and H 2 O. [Crystal structure] tetragonal system, often a pseudo-equal crystal system; [Form] The leucite crystals usually seen still retain the shape of the equiaxed crystal system (as a secondary image) (Fig. G-54), which is a complete tetragonal octahedron {211}, sometimes {100} and { 110} the shape of the poly. The joint surface of the polycrystalline twin crystal is (110), and the twin crystal stripes are sometimes seen on the crystal surface. Often in the form of granular aggregates. Figure G-54 white garnet crystal [Physical properties] often white, gray or furnace gray, sometimes with a pale yellow tone; streaks are colorless or white; transparent; glass luster. No cleavage, the fracture is greased. Hardness 5.5 to 6. The relative density is 2.4 to 2.50. [Cause and occurrence] Produced in some of the potassium-rich and silicon-poor effluent rocks and superficial diagenes, usually appear as phenocrysts. The leucite is often symbiotic with alkaline pyroxene and nepheline, and is not normally symbiotic with quartz because when it is formed, potassium feldspar will form if excess SiO 2 is present. [Identification characteristics] can be used as an identification feature with its complete tetragonal, triangular shape, ash-like color and its origin. [Main use] It can be used as a raw material for extracting potassium and aluminum .

a 0 = 1.304 nm, c 0 = 1.385 nm; Z = 16. When the temperature is above 605 ° C, it is converted into an equiaxed crystal variant (β-leucite), a 0 =1.343 nm.
Tungsten carbide grits are small particles or granules of tungsten carbide, a compound made up of tungsten and carbon atoms. They are extremely hard and have a high resistance to wear and abrasion, making them useful in a variety of industrial applications.
Tungsten carbide grits are often used as abrasives in cutting tools, grinding wheels, and sandpaper. They can also be used as an additive in metal alloys to improve their hardness and wear resistance. Additionally, tungsten carbide grits are used in the mining and drilling industry for rock drilling and excavation.
These grits are available in different sizes and shapes, such as spherical or irregular particles, depending on the specific application. They are typically produced through a process called sintering, where Tungsten Carbide Powder is heated and compressed to form a solid material.
Overall, tungsten carbide grits are highly valued for their hardness, durability, and resistance to wear, making them essential in various industries where high-performance materials are required.
