Phlogopite is divided into dark phlogopite ( brown or green in various shades ) and light phlogopite ( pale yellow in various shades ). Light-colored phlogopite is transparent and has glass luster; dark-colored phlogopite is translucent. Glass luster to semi-metal luster, the cleavage surface is pearl luster. The sheet is elastic. Hardness 2─3. The proportion is 2.70--2.85. Not conductive. Colorless or brownish-yellow under microscope transmission light. The main performance of phlogopite is slightly inferior to muscovite, but it has a high heat resistance and is a good heat-resistant insulating material.

Vermiculite is used to hatch eggs, especially reptile ones. The eggs of all kinds of reptiles, including geckos, snakes, lizards and even turtles, can be hatched in expanded vermiculite, which in most cases must be wetted to maintain humidity. Depression is then formed in the vermiculite, which is large enough to hold reptile eggs and ensure that each egg has enough space to hatch.

Vermiculite is a silicate mineral, which is a mica sub-organism. Its main chemical composition: 22MgO · 5Al2O3 · Fe2O3 · 22SiO2 · 40H2O. The theoretical molecular formula after roasting and expansion: ( OH) 2 (MgFe) 2 · (SiAlFe) 4O104H2O.

Nano active calcium carbonate is a kind of superfine calcium carbonate powder whose particle size is in the range of nanometer (1-100 nm). It has many special properties after being treated by surfactant. Nano active calcium carbonate is a kind of functional inorganic filler, which not only can increase product volume and reduce product cost, but also has excellent reinforcement performance.

Active calcium carbonate is a kind of product, which is made of common superfine calcium carbonate powder as raw material, added with saturated fatty acid and coupling agent for surface treatment, and treated by surface activation equipment. It has low water content, good dispersion, non agglomeration, low oil absorption value, good hydrophobicity and lipophilicity. 

Silica micropowder is a kind of inorganic non-metallic mineral functional powder material, which is made of natural quartz ore and fused quartz and processed by color separation, acid leaching, flotation, magnetic separation, grinding and grading. It has good temperature resistance, acid alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, high purity, high hardness and other excellent properties.

Negative ion powder is a general term for powder materials that can generate air negative ions. Anion powder is usually composed of rare earth elements, tourmaline powder and other substances . Some are made by mechanochemical compounding of rare earth salts and tourmaline ; some are made of natural mineral tourmaline , which is made by ultrafine crushing, gel coating modification, ion exchange doping and high temperature activation, etc. ; Some are directly extracted and ground from rare earth ore powder or waste slag .   

Calcite powder is bicarbonate, short for "heavy calcium carbonate".  It is a white powder processed with high-quality calcite as its raw material. Heavy calcium has high whiteness, good purity, soft hue and stable chemical composition. Therefore, heavy calcium is a good filler commonly used in industry. Heavy calcium is generally used as a filler, and is also widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, paper, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc. To increase the volume of products and reduce production costs. Used in rubber, it can increase the volume of rubber, improve the processability of rubber, play a semi-reinforcing or reinforcing role, and can adjust the hardness of rubber. In addition to supplying heavy calcium like calcite powder, we also have light calcium carbonate powder in stock.

Cobblestone There are natural pebbles and machine-made pebbles. The natural pebbles are from the river bed. The colors mainly include gray, cyan and dark red. After cleaning, screening, sorting and other processes. And the mechanical grinding pebble surface is smooth and wear-resistant. At the same time, it can be made into various specifications of pebbles according to different requirements of users. It is widely used in pavement, Park rockery, bonsai filling materials and so on.
