Emery, SiC, also known as silicon carbide. Pure is a colorless crystal. Density 3.06~3.20. It's very hard, about 9.5 degrees Morse. Generally, it is a colorless powdery particle. After grinding, it can be used as grinding powder, polishing paper, and friction surfaces for grinding wheels and whetstones. It is made by heating sand and carbon in an electric furnace.

Alumina powder is made of liquid aluminum hydroxide by extrusion solidification, which contains a variety of elements, and the content is high, the overall density is higher than the general aluminum powder. The surface of alumina powder is closer to the ideal surface than that of other metal powders, so it has good exhaust performance. The particle size of alumina powder is generally 90-100 microns, has good suspension, no load charge, can be oxidized at low temperatures, and has excellent electromagnetic characteristics.

Composite granite sheet is a kind of raw material in high-grade granite paint (paint), composite granite sheet is the introduction of green thermal insulation, it is composed of inorganic materials, high molecular polymer, non-ionic additives, interface active agent, color and shape size completely imitation of natural granite stone color and size of the particles.

Medical stone is a kind of natural ore with porous, light weight and high temperature resistance. It is widely used in the fields of building materials, agriculture, horticulture, fireproof materials and industrial filtration, and plays an important role.

Industrial alumina is prepared from bauxite (AlzOs-3H2O) and diaspore, and A1203, which requires high purity, is generally prepared by chemical methods. A1203 has a lot of homogenous crystals, there are more than 10 known, there are mainly 3 crystal types, namely A-Alzos, B-AlzOs, Y-AlzOs. Among them, different structures and properties are different, and it is almost completely converted into a-AlzO3 at high temperatures above 1300℃.

Volcanic stone (volcanic rock or pumice) is a kind of glassy lava with dense pores formed by the rapid expansion of internal gas due to the sharp reduction of pressure after the sudden cooling of magma during the volcanic eruption. The pore volume accounts for more than 50% of the rock volume. It is called pumice because of its many pores, light weight and ability to float on the surface of the water. It is characterized by high strength, heat preservation, heat insulation, sound absorption, fire protection, acid and alkali resistance, corrosion resistance, and no pollution, no radioactivity.

Glow Stones absorb either natural or artificial light and then emit that light as a soft glow during darkness. Exposure of around 30 minutes will give a glow time of approximately 6 – 8 hours. The glow starts off brightly and diminishes as the night progresses. The photoluminescent compound, strontium aluminate which makes the stones glow has a cycle life of at least 10 years.

Just when you thought you were going to install another exposed aggregate pool deck, your clients inform you they want the concrete to “glow” with stone accents. Don’t hit the panic button! If you’ve never worked with a glowing medium before, glow-in-the-dark stones in concrete can be a breeze. Glow stones are applied in exposed aggregate finishes in the same way as other decorative aggregates such as seashells and tumbled recycled glass.

In this paper, activated carbons (ACs) with high specific surface areas were successfully synthesized by simple one-step carbonization-activation from paulownia sawdust biomass, and the effects of the synthetic conditions on their CO2 capture capacity were investigated as well.

Vermiculite is a natural, inorganic, non-toxic mineral that expands under high temperature. It is a relatively rare mineral, belonging to the silicate group. Its crystal structure is monoclinic crystal system, and its appearance is similar to mica. Vermiculite is produced by the hydration of certain granite.

Everyone seems to be jumping on the mineralF. "People think mineral means natural, so they are drawn to it," dermatologist Francesca Fusco, MD, says.Many people find out about mineral makeup when they want to go "green" with their cosmetics. Cosmetic chemist Jim Hammer of Mix Solutions in Uxbridge, Mass., says, "With the current interest in safe, natural, and organic products, the mineral makeup approach is very popular. And the category appears to be continuing to grow."

Silica fume is a fine particle by-product generated during the smelting process of silicon ferroalloys in electric arc furnaces.

Alumina, chemical formula Alz0s. It is a high-hardness compound with a melting point of 2054 ° C and a boiling point of 2980 ° C. It is an ionic l crystal that can be ionized at high temperatures and is often used in the manufacture of refractory materials.

Green zeolite, the scientific name of dehydrated green bubble zeolite, is a natural mineral, by zeolite ore through high temperature refining and dehydration treatment. Zeolite is widely used in various fields because of its special crystal structure and chemical composition.
