Dandong brucite manufacturer has good quality

Dandong brucite manufacturer has good direct supply quality and wide application. Fengcheng Huafeng brucite Mining Co., Ltd. is a professional manufacturer of brucite, brucite flame retardant and brucite desulfurizer. The service attitude of the manufacturer is very good, the product quality is also good, the product is worthy of your possession. New fresh surface and fracture glass luster, cleavage surface pearl luster, brucite silk luster; transparent. The cleavage {0001} is very complete. The hardness is 2.5. The thin pieces are flexible and flexible. The relative density is 2.3 ~ 2.6. Thermoelectricity. The whiteness of massive brucite can reach 95%. Polariscope: abnormal interference color red brown instead of normal primary yellow or orange. The interlayer is maintained by a weak hydrogen oxygen bond, forming a layered structure. Mg oh was not octahedral, but flattened along the c-axis. The thickness of Mg Oh changed from 0.247nm to 0.211nm. Due to its structural characteristics, brucite has low hardness and ∧ {0001} extremely complete cleavage. Under the influence of stress, ductility can be positive or negative. One axis crystal (), but two axis crystal, 2V? 25?. The refractive index ne = 1.5705 ~ 1.5861, no = 1.5612 ~ 1.570, and the difference between NE and no decreases after heating. Mechanical properties: the tensile strength of brucite is 902mpa, which belongs to medium strength fiber material. The modulus of elasticity is 13800mpa, which has certain brittleness. The Vickers hardness is 50.4 ~ 260.5, and it has obvious anisotropy. Easy to grind into fine powder. The theoretical relative density is 2.39. Complex triangular hemihedral crystals, d3d-3m (l33l33pc). The crystal is plate or leaf like. Common simplex: parallel double-sided C {0001}, hexagonal column m {1120}, rhomboid R {1011} Q {0113} or {2021}. The crystals are usually plate-shaped, fine scale, round and irregular granular aggregates, sometimes parallel fibrous aggregates, called brucite. There is structural distortion in brucite. When FeMn is mixed in, it is greenish yellow or maroon; the tangent value of dielectric loss angle is 0.105. The dielectric loss tangent increases by 54% and 2.7 times respectively.Electromagnetic properties: the mass resistivity of brucite is 8.82? 106 Ω? G / cm2, the volume resistivity is 5.9? 106 Ω? Cm, the surface resistivity is 3.6 ~ 4.5? 106 Ω, the resistivity is anisotropic; the resistivity increases when heated. The dielectric constant is 4.7 ~ 5.4 (1MHz); at low frequency (50Hz) and medium frequency, the dielectric constant increases with obvious directionality; it is characterized by its low hardness and (0001) complete cleavage. In the ternary system, A0 = 0.313nm, C0 = 0.474nm; Z = 1. Brucite structure is one of the important layered structures. In the structure, (OH) - is close packed in six directions. Mg2 is filled in the octahedral space separated by the stacking layer. Each mg is surrounded by six Oh's, and each Oh side has three mg's. [Mg (OH) 6] octahedron ∧ {0001} is connected into layers in a common arris way
