Description

A kind of cordierite kiln furniture saggar and preparation method thereof
Technical field
A kind of cordierite kiln furniture saggar and preparation method thereof, belongs to technical field of refractory materials.
Background technique
Saggar is the kiln furnitures being used for a long time on a kind of kiln, is expendable material.In ceramics, building materials, chemical industry, metallurgy, glass The industrial applications such as glass are extensive.Saggar applied by present mostly makes bearing capacity receive limitation, and energy because sole mass is heavier Consumption is big, and diathermancy is poor, and easy to crack in use process, breakage rate is high, and service life is short.The machinery for how improving saggar is strong Degree, high temperature load softening temperature, resistance to thermal shocks, refractoriness, thermal conductivity, are present urgent problems to be solved.
Summary of the invention
The technical problem to be solved by the present invention is overcoming the deficiencies of the prior art and provide a kind of long using temperature height, service life Cordierite kiln furniture saggar and preparation method thereof.
The technical solution adopted by the present invention to solve the technical problems is: the cordierite kiln furniture saggar, which is characterized in that former Expect parts by weight composition are as follows: 10 ~ 15 parts of 3-1mm mullite M47,10 ~ 15 parts of 1-0mm mullite M47,2-1mm cordierite 16 ~ 20 Part, 7 ~ 12 parts of 150 mesh cordierite of partial size <, 8 ~ 13 parts of 0.5-0mm sillimanite, 7 ~ 13 parts of 200 mesh andalusite of partial size <, partial size < 240 4 ~ 7 parts of mesh silicon carbide, 5 ~ 10 parts of 240 mesh sub-white corundum of partial size <, 3 ~ 6 parts of micro mist of aluminium oxide CA 370C, the Suzhou 0.045mm 4 ~ 6 parts, 3.5 ~ 5.5 parts of paper pulp, 0.3 ~ 0.6 part of phosphoric acid, 0.3 ~ 0.6 part of dextrin of soil.
It is good that cordierite has many advantages, such as that thermal expansion coefficient is small, anti-thermal shock stabilization wins, and is mainly used for the production of ceramic kiln furniture.
