Abstract
The invention belongs to ceramic fields, more particularly to a kind of drop resistant ceramic and preparation method thereof, kaolin, gneiss, manganese spar, orthoclase, nanometer zirconium disilicide, red corundum, magnesite, mullite crystal whisker, yttria-stabilized zirconia, carbon fiber, wheat stalk powder, sawdust, corn flour, nano-antibacterial powder.Aggregate, auxiliary material and other raw materials are prepared into greenwave, are sintered after soaking glaze, sintering temperature is 500~1300 DEG C.A kind of drop resistant ceramic provided by the invention and preparation method thereof, the material used increases intensity, alleviates total amount, and caking property is preferable between particle, and resulting ceramic has certain shock resistance, drop resistant.
Description
Technical field
The invention belongs to ceramic fields, and in particular to a kind of drop resistant ceramic and preparation method thereof.
Background technique
Ceramics are widely used in feeder, decoration, science because of the features such as its quality is hard, fine and closely woven, high temperature resistant, glaze colours are abundant
