Sri Lankan Silicon Dioxide Suppliers and Manufacturers

Silica sand,� also known as quartz sand, white sand, or industrial sand,� is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz â?? a chemically inert and relatively hard mineral. SiO2 grades at a 7 out of 10 on� Mohs hardness scale, making it ideal for use as� filtration media� and� abrasive blasting sands. Although quartz is often white or colourless, it can come in a wide range of shades. The colour of each sand deposit depends largely on the variety of minerals and rock detritus that make up the resource. In order to be considered a silica sand the material must contain at least 95% SiO2 and less than 0.6% iron oxide. If the sand does not meet this criteria, it will qualify as whatâ??s often called â??regularâ?? sand. Regular sand,� also known as feldspathic sand, brown sand, or construction sand, will always contain some silica, but only in amounts less than 95%. For example, typical brown sand used for� concrete applications� can contain up to 80% SiO2, along with varying amounts of iron, carbonate, potassium, and other trace elements/minerals.

The snow pea is an edible-pod pea with flat pods and thin pod walls. It is eaten whole, with both the seeds and the pod, while still unripened. Snow peas are a crunchy and delicious vegetable. While they can be eaten raw, they take just minutes to cook. The name "snow peas" may come from the vegetable's ability to withstand frost. They're generally planted no earlier in the spring than other pea varieties, and some gardeners keep them growing through autumn. Another theory behind the name refers to its white appearance in bright light. Snow peas can be grown in open fields during cool seasons and can thus be cultivated during winter and spring seasons. Storage of the pea with films of polymethyl pentene at a temperature of 5 C and a concentration of oxygen and carbon dioxide of 5 kPa augments the shelf life, and internal and external characteristics of the plant.
