Here are some criteria business owners can use when purchasing silica products.
Quality
When purchasing silica products, buyers should settle for those that have silica content of over 99%. Also, ensure the products have a low percent of impurities. Silica gel products should also be of high quality and made from silica that has been processed to form a rigid structure with high surface area.
Grain size
Business owners should stock various grain sizes to cater to diverse industrial customers. For instance, crystalline and angular grains are suitable for customers who intend to use them for sandblasting and metal work. At the same time, they should get silica with a fine grain suitable for the pharmaceutical and food industry.
Moisture content
Together with the grain size, moisture content also affects the market's choice of silica particles. At the same time, moisture content is usually high with particles that have fine grains. Low moisture content is ideal, especially for silica gel customers, because high moisture content ruined the product's efficiency as a desiccant.
Batch uniformity
This is the consistency in chemical and physical composition from one batch to another. It is very important, particularly for clients purchasing silica for industrial uses, because differences between batches can cause differences in product efficiency. Stock products with slight variations in grain size, purity, or color, as they can significantly affect how the product performs in various applications. For instance, sandblasting silica should be consistent to avoid disparities in surface finish during metal treatment.
Packaging
