Abstract

The invention provides a ceramic composition and a preparation method thereof. The ceramic composition is prepared from the following components in parts by weight: 1 to 8 parts of bamboo charcoal powder, 10 to 15 parts of sepiolite, 1 to 5 parts of zinc borate, 1 to 5 parts of tourmaline crystal particle and 40 to 60 parts of clay. The ceramic composition with high adsorption performance, which is prepared by the preparation method, has a larger specific surface area and higher illumination self-cleaning capacity, can be used for effectively adsorbing harmful gases of formaldehyde, benzene and the like, and is used for improving air quality; moreover, the preparation method is simple and is suitable to the industrialized production.

Description

technical field [0001] The invention relates to the technical field of composite ceramic materials, in particular to a ceramic composition and a preparation method thereof. Background technique [0002] Tourmaline is a silicate mineral with a ring structure of aluminum, iron, sodium, magnesium, and lithium, which is characterized by boron. It is black or gray-black, and has a thick needle, bundle, or radial structure. Tourmaline has special pyroelectricity and piezoelectricity, has high far-infrared radiation and negative ion release ability, and contains a variety of trace elements beneficial to human health. It is widely used in drinking water activation, air purification, sewage treatment, Ceramics, building materials, daily chemicals, electronics, textiles, health care products, beauty cosmetics and other fields. [0003] Bamboo charcoal has a rich honeycomb microporous structure. This microporous structure makes bamboo charcoal have a large specific surface area, showi...
