Product Description Product DescriptionCorundum mullite saggar is a unique ceramic material composed mainly of two minerals: corundum (aluminum oxide) and mullite (aluminum silicate). The term "saggar" refers to a protective container designed to hold and support fragile or delicate items during high-temperature treatments.The introduction of corundum mullite saggars has been significant in improving the efficiency and quality of high-temperature processes, such as firing ceramics in kilns or sintering powdered metals. The saggars act as protective enclosures that shield the products from direct contact with flames or other reactive atmospheres.Features:1.High temperature resistance: Corundum mullite saggars can withstand extreme temperatures without melting or deforming, ensuring the stability of the enclosed items during the firing process.2.Chemical inertness: These saggars exhibit excellent resistance to chemical reactions, ensuring that the materials being processed remain unaffected by the surrounding environment.3.Thermal shock resistance: They have good thermal shock resistance, preventing cracking or damage when subjected to rapid temperature changes.ItemTesting Condition95% AL2O399% AL2O399.7% AL2O3Physical propertiesDensityg/cm3 >3.63.893.96Moisture absorption% 000Mechanical propertiesROHS Hardness ≥85≥89≥89Flexural strengthpsiX10320oC358550550Compressive strengthpsiX10320oC2068(300)2600(377)2600(377)Fracture toughnessMpa.m3/2K(l c)4.35.66.0Thermal propertiesMaximum use temperatureoC 145016001650Thermal expansion coefficient1X10-6/oC(25-1000oC)7.67.98.2Thermal shock resistanceoCTc250200200Thermal conductivityw/mok20oC163030.4Electrical propertiesVolume resistivityOhm/cm2100oC>1013>1014>1014Dielectric breakdown strengthKV/mm 8.7(220)8.7(220)8.7(220)Dielectric constant(E)1MHz25oC99.79.Q1 : How can you control your quality?A1 : For each production processing, we have complete QC system for the chemical composition and Physical properties. After production, all the goods will be tested, and the quality certificate will be shipped along with goods. Q2 : What is your lead time? A2 : It usually needs about 15- 20 days after receiving the PO. Q3 : Do you provide free samples?A3 : Yes, free samples are available, generlly speaking, the buyer shall bear all the delivery cost. Q4 : What is your payments terms?A4 : We can accept 30% deposit, 70% balance to be against the BL copy or by LC, or other payment terms. Q5 : Can we visit your company?A5 : Yes, for sure, you are welcome to visit JUCOS company. Q6 : What standards do you have?A6 : Our products meet the standards, such as ASTM, ASME, AMS, DIN, JIS etc. The third party testing is all available for us.
