Gibbsite
[Chemical composition] A small amount of Fe 2+ and Ga 3+ are often substituted for Al3+.
[crystal structure] monoclinic system, 
 ; a 0 =0.864 nm, b 0 =0.507 nm, c 0 =0.972 nm, β=94°34′; Z=8. It has a brucite structure, but Al 3+ is only filled in a 2/3 octahedral void between each two adjacent OH - hydroxy ions to form a structural layer of coordination octahedron.
[Form] The single crystal is in the form of a pseudo-square plate. Usually it is a tuberculosis, a bean-like aggregate or a cryptocrystalline aggregate.
[Physical properties] white, often with gray, green and brown; glass luster, cleavage surface is pearl luster, aggregates and cryptocrystals are dim. The cleavage parallel {001} is extremely complete. Hardness 2.5 to 3.5. The relative density is 2.30 to 2.43.
[Origin] and occurrence mainly feldspar aluminosilicate formed by weathering. Part of the gibbsite is the cause of low temperature hydrothermal fluid. In the regional metamorphism, gibbsite becomes dehydrated by dehydration; in the deeper regional metamorphism, it can be changed into corundum ; if SiO 2 is present, it becomes aluminosilicate-containing mineral. .
[Main use] is the main ore mineral of aluminum. It can also be used to make refractory materials and high alumina cement raw materials.
EVA Deck Pad for kiteboard deck pad and SUP deck pad comes in two ways normally. One is full sheet for DIY, the other one is die cutting based on customized design.
The full sheet deck pad can be in 230cm x 90cm or 90cm x 90cm size. Customers can cut the deck pad based on their board size, then simply peel and stick since the EVA deck grip we offered it with 3M adhesive. Besides, it can be also used in any other application for traction like boat flooring, yacht flooring and etc.
