Shengxian Diatomite

Shengxian Diatomite

　　Product Name: Shengxian Diatomite

　　Alias: White Clay

　　Place of Origin: Shengxian County, Shaoxing City, Zhejiang Province

　　Functions: Low density, large porosity, strong adsorption capacity, with functions such as sound insulation, heat insulation, acid and alkali resistance, bleaching, and filtration assistance.

　　Product Introduction: Shengxian diatomite, commonly known as white clay or Guanyin soil, is mainly produced in 11 towns in Shengxian County, including Chongren, Chunlian, Puyi, Chengxi, and Chengjiao, covering an ore area of about 80 square kilometers. Large-scale mining began in 1958. Diatomite resembles chalk and comes in various colors such as white, blue, gray-white, gray-blue, brown-black, and yellow. It is a biogenic sedimentary rock that weathers into a flaky form. The soil has low density, large porosity, strong adsorption capacity, and functions such as sound insulation, heat insulation, acid and alkali resistance, bleaching, and filtration assistance, making it widely applicable. Shengxian diatomite is one of the dominant non-metallic mineral varieties in Zhejiang Province and ranks first in reserves nationwide. In 1990, Shengxian produced 50,000 tons of diatomite, which was sold to 23 provinces and cities across the country.

　　Product History: Shengzhou diatomite is one of the dominant non-metallic mineral varieties in Zhejiang Province, with reserves ranking first in the country and abundant resources. Its uses are extensive. However, large-scale organized mining began in 1958, when the main products were only raw diatomite blocks and simply processed ore powder. Starting in 1966, the production of diatomite insulation bricks and cement-mixed materials began. By 1984, a new type of energy-saving insulation material—microporous calcium silicate—was developed. For this purpose, four production plants were established, with an annual production capacity of approximately 10,000 cubic meters. The production of microporous calcium silicate marked the beginning of refined processing in the development and utilization of diatomite. Currently, the annual mining volume of diatomite exceeds 50,000 tons, and it is sold to 23 provinces and cities across the country, making it the most important production site for diatomite in the nation.
