Problems solved by technology
This application solves some shortcomings of the above-mentioned materials to a certain extent, but it also has some shortcomings. For example, the solution has poor plasticity and cannot be formed arbitrarily. It can only be formed by hydraulic dry powder with a hydraulic press. The wall is relatively thick, so that the weight per unit volume of the product of this scheme is still relatively large, which can only be used in chemical fillers

Embodiment 1
[0013] Composition of raw materials (expressed in weight percent): 50% of magnesia clay, 12% of floating pearls, 8% of perlite powder, 20% of coal powder, and 10% of local clay.
[0014] According to the above formula, put the raw materials into the ball mill, add appropriate amount of water for ball milling, and squeeze dry to become the material. Then: 1. Vacuum mud mill can be used to extrude semi-finished chemical fillers of various shapes; 2. Can be kneaded into semi-finished catalyst carrier semi-finished products; 3. Can be dried and pressed into ceramic filter brick semi-finished products by hydraulic press; 4. It can be made into semi-finished products of ceramic heat sinks in cooling towers of power plants; 5. It can be made into semi-finished products for sound insulation on expressways. Then the above-mentioned semi-finished products are sintered into lightweight ceramic products in different fields of use.

Description
technical field [0001] The invention relates to a ceramic material and its manufacturing method and application, which can be used in chemical industry. Metallurgy, energy, environmental protection, transportation, building materials and other fields. Background technique [0002] In the current existing technology, the materials that can be used in the fields of chemical industry, metallurgy, energy, environmental protection, transportation, building materials, etc. include ordinary ceramics, plastics, metals, wood, and other composite materials. These materials have different shortcomings. For example, ordinary ceramics have a large proportion, are easy to break, are not easy to cut, and are not resistant to rapid cooling and heat; plastics are not resistant to high temperatures, are easy to age, and have a short service life; metals have a large proportion, poor thermal insulation performance, corrosion resistance or expensive cost; High, and not conducive to national pr...
