Diatomite(diatomaceous earth) is a kind of siliceous rock, mainly distributed in China. It is a kind of biogenic siliceous sedimentary rock, which is mainly composed of the remains of ancient diatoms. Its chemical composition is mainly SiO2, which can be expressed as SiO2 • nH2O. Its mineral composition is Opal and its varieties.
Application: It is used in drilling, petroleum, medicine, brewing, building materials, pesticide, chemical fertilizer, rubber products, brake, etc.
Bentonite is a kind of water bearing clay ore mainly composed of montmorillonite, because of its special properties. Such as: swelling, cohesiveness, adsorption, catalysis, thixotropy, suspension, cation exchange, etc.
PH value 8.9-10
Ca-Bentonite contains a small amount of feldspar, quartz, bedite, calcite and pyroclastic materials. The main chemical components are SiO2, Al2O3 and a small amount of Fe2O3, MgO, Cao, K2O, Na2O and TiO2.
Color: red, black. Size: 2-3mm, 5-8mm, 3-5mm, 8-12mm, 1-3cm, 3-5cm, 5-8cm, 10-50cm. Style: stone, particle, powder.
Plate crystal, small hardness, near right angle intersection of complete cleavage, high density, non foaming in the presence of hydrochloric acid.
Cenosphere(floating bead) is a kind of fly ash hollow ball which can float on the water surface. It is gray white, thin and hollow with light weight. Its volume weight is 720kg / m3 (heavy weight), 418.8kg/m3 (light weight), particle size is about 0.1mm, its surface is closed and smooth, its thermal conductivity is small, and its fire resistance is ≥ 1610 ℃. It is a good temperature keeping refractory material, widely used in the production of light castables and oil drilling.
