Detailed Description

Product: Crucible Material: Si3N4 Applications: Metal smelting, chemical and solar power industries. Descriptions: This product is manufactured under CIP (Cold Isostatic Pressing) and hot-press based special sintering methods. Walsun si3n4 crucible is with high consistency and good equality. Due to its strong resistance to liquid metal corrosion, it is the most suitable solution in high purity smelting industries e.g. solar power and biology. Dimensions: Customized Advantages: 1,Excellent resistance to strong acid, alkali and sea water; 2,Excellent high-temperature resistance. The strength and rigidity won't be changed at 1000C. 3,Non-magnetic and insulated. 4,light in weight (3.1-3.3 g/cm3). 5,High hardness and high Young's modulus. 6,Light in weight, and low eccentricity. 7,The Coefficient of Thermal Expansion is 3.2*10-6/K, which is 1/4 to steel. 8,It's a self-lubricating material. 9,High in mechanism intensity and toughness, low in heat conductivity.
