What is special-shaped ceramics, process characteristics and application introduction
In the modern collection world, some special-shaped ceramics are loved by many collectors. The company develops and produces various special and special-shaped ceramic components with high quality and high reliability for users, such as special-shaped shells, connectors and heating elements.

Porcelain in the traditional concept is square and round, but there are some porcelains that do not take the usual way, find a new way, and walk out of their own style, they are special-shaped porcelain.
Under the modern technology, the porcelain type breaks through the original specifications, and the design of creative ceramics is not based on common sense, and the creativity is not constrained by thinking. This is the design concept of modern special-shaped porcelain. In terms of shape, it has the dual characteristics of its practicality and partial ornamental. The beauty is the distinctive place of the special-shaped porcelain, and the unique appearance makes it endowed with a distinctive mark.
Beautiful in shape, unique in creativity, and the artist's brain is wide open, giving porcelain another life, peculiar and public, and full of design. The full or flat porcelain body and irregular patterns give people a simple and unique style impression. Changeable appearance, breaking the traditional design ideas, with simple patterns, it is a piece of unique charm.
Typical applications of ceramic fiber shaped parts ◎ 1. Non-ferrous metal melting grooves, groove liners, casting caps; ◎ 2. Sump and launder in the aluminum product industry; ◎ 3. Thermal radiation insulation of civil and industrial heating devices Heat; ◎ 4. Industrial kiln observation hole, thermometer temperature measurement hole; ◎ 5. Industrial kiln door; ◎ 6. Electrical and mechanical equipment connection gasket.
The density of ceramic fiber special-shaped parts is divided into heat-insulating and sealing type and fire-blocking and heat-insulating type. The thermal conductivity of fire-blocking and heat-insulating ceramic fiber-shaped parts is lower than that of heat-insulating and sealing products, and the price is relatively high. The bulk density of ceramic fiber special-shaped parts is 300-400kg/m3, and the density of about 300kg/m3 is a relatively conventional specification. It is widely used because of its good hardness, refractoriness, and thermal insulation performance; 400kg/m3 The density is often used to prevent fire in the furnace , windshield, temperature zone and other areas that are in direct contact with the flame, belong to the extra hard type.
The surface pretreatment of ceramic fiber special-shaped parts uses chemical or physical methods to flatten the surface of ceramic fiber special-shaped parts, and smooth the surface through mechanical treatment. The surface pretreated ceramic fiber special-shaped parts, under certain process conditions, oxidize the surface to form a dense and porous AL203 film layer. The pores of the porous oxide film generated after oxidation are closed, so that the anti-pollution, corrosion resistance and wear resistance of the oxide film of the ceramic fiber special-shaped parts are enhanced. The oxide film is colorless and transparent, and the strong adsorption of the oxide film before sealing is used. , and some metal salts are adsorbed and deposited in the pores of the membrane. The formation of thermal shock resistance of ceramic fiber special-shaped parts: the addition of refractory fiber cotton with good dispersion in the production process of ceramic fiber special-shaped parts can effectively improve the strength and thermal shock resistance, and the crystallization and The bridging effect of the ceramic phase on both sides of the interface can prevent the further expansion of the matrix crack, and at the same time does not affect the thermal shock energy dispersion and absorption through the interface, so that the material has high thermal shock resistance.
