Phu Yen diatomite is bio-origin sediment formed in fresh water areas due to the decomposition of diatomeae algae. Diatomite algae absorb water-soluble silicic acid and convert it into opal form, amorphous SiO2 form. With special algae frame structure, Diatomite has great adsorption capacity, high porosity. Therefore, Diatomite has many applications in agriculture, crop protection andRead more
