Abstract

The invention discloses a composite ceramic material, which is prepared from the following raw materials in parts by weight: 50 to 80 parts of zirconium dioxide, 30 to 50 parts of silicon dioxide, 4 to 8 parts of tungsten carbide, 5 to 10 parts of barium titanate, 2 to 4 parts of magnesium diboride, 1 to 3 parts of cerium dioxide, 1 to 3 parts of titanium dioxide, 2 to 5 parts of aluminum oxide, 0.1 to 0.5 part of yttrium oxide, 0.2 to 0.6 part of hafnium oxide, 5 to 10 parts of talcum powder, 3 to 5 parts of Chaohu sand, 5 to 8 parts of aluminum dihydrogen phosphate, 1 to 3 parts of steel fiber, 3 to 8 parts of carbon fiber, 4 to 6 parts of basic magnesium carbonate, 5 to 10 parts of crystallized glass powder, 15 to 20 parts of Ukrainian wax raw ore, 20 to 35 parts of hiddenite, 5 to 8 parts of lithium carbonate and 3 to 6 parts of aluminum nitrate. The zirconium dioxide, the silicon dioxide, the Ukrainian wax raw ore and the hiddenite are used as major materials, so that the hardnessis greatly improved; the antioxidation characteristic is realized; other raw materials are assisted, so that the whole material has the characteristics of acid resistance, alkali resistance and sharpquenching and sharp heating resistance; the thermal stability can reach sharp quenching of 550 DEG C to 20 DEG C without cracking; the quality index exceeds the standard requirements of GB / T258-2002.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a composite ceramic material. Background technique [0002] The Chinese invented pottery as early as about 8000-2000 BC (Neolithic Age). The utensils fired with clay are called pottery, and the utensils fired with china clay are called porcelain. Ceramics is the general term for pottery and porcelain. The ancients called ceramics Ou. Any utensils made of two different types of clay, pottery clay and porcelain clay, as raw materials, through batching, molding, drying, roasting and other processes can be called ceramics. [0003] The development history of ceramics is an important part of the history of Chinese civilization. As one of the four ancient civilizations, China has made outstanding contributions to the progress and development of human society. Among them, the invention and development of ceramics has unique significance. Various dynasties in Chinese history have ce...
