Silica powder, silica Jiangmen abundance Schroder Mining

Diamond and moissanite relatively difficult to distinguish non-professionals. Diamond stronger than the color of fire, hardness 9.25, the closest diamonds, thermal analyzer to identify the same reaction and diamonds. With the exception of the points are relatively different density (3.22), Diamond 3.52.10 magnification can be seen clearly facet edge ghosting (dr birefringence of 0.042). Of course, the color of fire (0.104) higher than diamond (0.044) can be the difference. Here are ways to professional recognition, for reference. 1. synthetic moissanite visually strong color of fire than diamonds, but diamonds are often less bright. 2. Synthetic moissanite diamond color up to the equivalent h, i color, and viewed from the pavilion has obvious green silica stone, gray tones. 3. In this synthetic moissanite LuoShi 3.33g / cm heavy fluid floating diamonds sink. 4. synthetic moissanite in orthogonal polarizing microscope, rotating 360 was four out four dark non-homogeneous body extinction phenomenon. Diamond was full dark homogeneous body extinction phenomenon. 5. zoom Attorney hydrated silica, synthetic moissanite common slender white needle containing, from the sail on the sharp end of the lumbar facet visible near the ridge has ghosting, shaped like a lotus; tilted back from the edge of the desktop reflective also ghosting. It contains natural crystalline diamond-shaped body, clouds, cracks and other inclusions, and no ghosting silica, waist common original crystal surface. 6. synthetic moissanite diamond polishing less, than the rounded ridge or polished texture visible adjacent facets parallel to each other. 5 ways to use the first, second combined sixth and methods to determine, generally very accurate. Another name of the main purposes of the silica is silica quartzite, due to its unique fire-resistant properties, is widely used in the construction industry at this stage, and in addition can also be chemically processed into a variety of salts and silicide series, so this kinds of high purity silica is also known as silica. Silica resources are more abundant in our country, and mining and storage technology than mature, its use varied, in addition to the two previously mentioned, silica can also be processed into sodium silicate, and sodium silicate is the largest amount of chemical , one of the most extensive use of raw materials. Also silica also can be made into a variety of boards and metal products adhesives, soap and washing powder is added ingredients, or the cotton textile industry dyes, and bleach, while the cloth fireproof treatment. In food preservation also has a unique feature, after processing the modified silica can also be made wall paint and protectants. The silica as silicon dioxide is widely used in electronics manufacturing and optical fiber. Silica powder, silica Jiangmen, Feng Schroder mining by Chongyi County 聂都丰 Schroder Mining Limited.
