S10 Technical Ceramics

There is no strict classification of technical ceramics, and the names at home and abroad are not consistent. They are also called advanced ceramics, new ceramics, high-tech ceramics, special ceramics, etc. In short, it generally refers to special ceramics that are different from general ceramics. Its main varieties include electronic ceramics, biological ceramics, superconducting ceramics, optical ceramics, porous ceramics (honeycomb ceramics, foam ceramics), composite ceramics, ceramic coatings and so on. Among them, electronic ceramics - also known as radio ceramics, refer to ceramic materials for electronic components and devices in the electronics industry. The commonly used electronic ceramics include magnetic ceramics (such as manganese zinc, nickel zinc, magnesium manganese, barium ferrite, etc.), piezoelectric ceramics (such as barium titanate porcelain, lead zirconate titanate porcelain, etc.), pressure-sensitive ceramics (such as zinc oxide, etc.), capacitor ceramics (such as calcium titanate, magnesium titanate porcelain, etc.), ferroelectric (such as barium titanate porcelain, etc.), conductive ceramics (such as zirconia, tin oxide porcelain, etc.), and device porcelain which is also called insulating ceramics (such as steatite porcelain, forsterite porcelain, alumina porcelain, barium feldspar porcelain, etc.).

Due to the wide variety of technical ceramics, various types of kilns are used, such as tunnel kiln, roller kiln, pusher kiln, shuttle kiln, bell/beehive kiln and so on. The firing temperature, soaking time, and firing atmosphere are different, and the fuels used are different too. Therefore, the kiln furniture materials used in this industry vary a lot. The mainstream kiln furniture includes pusher batts, base batts, cover batts, saggars and radiant batts, etc. The materials used include corundum-mullite, cordierite-mullite, silicon carbide, silicon nitride, zirconia series, etc. The solutions of Trend kiln furniture in various kilns for technical ceramics are as follows: ①under oxidizing atmosphere: below 1300℃, cordierite-mullite kiln furniture; above 1300℃, corundum-mullite kiln furniture. ②under neutral atmosphere or inert atmosphere: below 1250℃, cordierite-mullite kiln furniture; above 1250℃, corundum-mullite kiln furniture. ③under weak reducing atmosphere: below 1200℃, cordierite-mullite kiln furniture; above 1200℃, corundum-mullite kiln furniture. ④under strong reducing atmosphere: below 1150°C, cordierite-mullite kiln furniture; above 1150°C, corundum-mullite kiln furniture.
