Product Description Gongtao company can make various crucibles and saggers made of high alumina, with different shapes. And we can also custom based on the requirement.Series:Alumina ceramic crucibleCorundum ceramic crucibleArc alumina crucibles(high form alumina crucibles)Cylindrical alumina ceramic cruciblesRectangular cruciblesSpecial shaped cruciblesAlumina saggersSpecification: 5ml 10ml 15ml 20ml 25ml 30ml 50ml 100ml 150ml 200ml-2500mlPoints:High alumina purity: Al2o3>99%, good corrosion resistance.High temperature resistance, 1600C in long use, 1800C in short use.Good thermal shock, no easy to crack.High slip casting densityMain purpose of crucible and sagger is as a container for analysis and firing of material and product applied in various industries. For example: Analysis of coal, melting of the metal, analysis and firing of chemical raw materials, analysis and melting of glass, analysis and firing of rare earth materials and mineral, firing of highTemperature items such as ceramic products and melting of single-crystal raw materials.Under normal circumstances, firstly put the items which need to be analyzed and fired into the crucible or sagger. Then heat. The speed of heating and drop in temperature are according to the characteristics of equipment and products, fast or slow. Because of the thermal expansion of raw material which the crucibles and saggers are made of, too quick heating or cooling will easily lead to cracking of the crucibles and saggers. The best way is slowing down, which can prolong the life of them.ITEMNOSPECIFICATION m/mWEIGHTCAPACITYSTOCKODHEIGHTTHICKNESSKGC.C100120251.50.015Available100225301.50.01510Available100330302.00.02515Available1003-230402.0 Available1003-330502.0 Available1004353520.03525Available1004-235502 Available100540402.50.05535Available100645452.50.0750Available100750502.50.0975Available1007-250602.5 1007-350802.5 1007-4501002.5 100855552.50.11100Available1008-2551002.5 Available100960603.00.15130Available1009-2601003.0 Available1009-3601203.0 101065653.00.18170Available1010-2651003.0 Available101170703.00.21215Available101275753.00.24270Available101380803.00.27330Available101485853.00.31400Available101590903.00.35480Available10169595 3.00.40570Available10171001003.50.50650Available10181051053.50.55765Available10191101103.50.60880Available10201151154.00.661020Available10211201204.00.811140 10221251254.00.891300 1023130 1304.00.961450 10241351354.01.041650 10251401404.01.121850 10261451454.01.202050 10271501504.51.442250 10281601604.51.642750 10291701704.51.863350 10301801804.52.094000 10311901905.02.584700 10322002005.02.875500 10332102105.03.176400 10342202205.03.487400 10352302305.03.818500 10362402405.04.159700 10372502505.05.201200 Item Chemical componentAl2O3≥99R2O≤0.2Fe2O3≤0.1SiO2≤0.2Vol.density(g/cm 2 ) ≥3.80Apparent Porosity(%)<1Bending Strength(Mpa)>350Compression strength(Mpa)>12000Permittivity ∑(1MHz)2The max.operating temperature1800
