🔔Product name: Boron nitride crucible, boron nitride ark 🔔Material: Purity of boron nitride 99.6% 🔔Product Specifications: 2ml (16mm*20mm)/3ml (20mm*18mm)/5ml (24mm*22mm)/10ml (28mm*30mm)/20ml (32mm*32mm)/50ml (47mm*45mm)/100ml (58mm*58mm)/50mm*15mm*15mm/50mm*20mm*20mm/100mm*15mm*15mm/100mm*20mm*20mm/100mm*25mm*25mm/100mm*40mm*20mm 🔔Features: Boron nitride ceramic products fired at high temperature and high pressure, with good thermal, electrical and chemical properties; Boron nitride does not infiltrate most molten metals, is chemically inert, and is used in a non-oxidizing atmosphere at temperatures up to 2200℃. Boron nitride has the advantages of neutron absorption, infrared penetration, high temperature lubricity and processability. 🔔Scope of application: Widely used in solar photovoltaic, semiconductor, high temperature furnace heat treatment, metal metallurgy, new energy, aerospace and other scientific and technological fields. 💖Description: Boron nitride crucible, purity 99.6%, nitrogen, argon protection temperature 2200 degrees Celsius; Vacuum environment temperature 2000 degrees Celsius; Below 900 degrees Celsius in the air; Reducing atmosphere is not recommended, thermal conductivity 50W/mk. Boron nitride crucible can be used for sintering and melting metal materials, rare earth, ceramics and other materials, high purity, high density, thermal shock resistance, corrosion resistance, and many metal, ceramic materials do not react and do not bond, the use of temperature 2000 degrees Celsius, 1500 degrees Celsius 10 minutes of rapid cooling to room temperature 100 times will not crack, 1000 degrees Celsius cold water does not crack, Oxidation resistance temperature of 900 degrees Celsius, can replace graphite, alumina crucible. The boron nitride ceramic evaporation boat is equivalent to an internally heated ceramic evaporator with a wide range of metal evaporation, which can be used for the evaporation of Au, Ag, ln, Sn, Sb, Bi, Cd, Cu, Pb, Zn, Co, Ni, Fe, Mn, nickel-chromium alloy and high permeability magnetic alloy. Most metals can be completely evaporated without loss. The boron nitride conical crucible and tungsten wire basket are used together, and the evaporation basket can be used repeatedly.
💖Product characteristics: Boron nitride (BN) has high melting point, good thermal conductivity, good insulation, high bending strength, good thermal shock resistance, chemical corrosion resistance. It still has quite stable high frequency dielectric properties at high temperature. The advantage of BN is that it has excellent machining performance and can be processed into porcelain parts with complex shape and high precision. Therefore, it is widely used in composite conductive ceramic evaporation boats, high temperature crucible, sputtering targets, high temperature high frequency and plasma arc electrical insulators, electronic module heat dissipation devices, traveling wave tube collection and heat sinks, transistor heat sinks, semiconductor packaging heat sinks, high frequency induction furnace materials and atomic reactor structural materials, anti-photoelectric radiation, chemical radiation, nuclear radiation materials and radar transmission Windows .
💖Available materials: 1, ferrous metal, iron, copper, stainless steel, bismuth, wrong, aluminum, antimony, tin, cadmium, lead, nickel, zinc, brass, indium, magnesium, etc.; Glass melt, sodium glass, cryolite and other silicon; Molten salt: slag fluoride. 2, does not react with water, acid and alkali at room temperature. Slowly hydrolyzed to boric acid and ammonia by co-boiling with water. 3, alloy FE-CO-NI-SI and CO-ZR-NB.
💖Unavailable materials: 1, antimony trioxide, chromium setoxide, molybdenum oxide, arsenic trioxide, titanium carbide. 2. High lead glass glaze melts in 800-950 degree air and erodes BN, but has no reaction in nitrogen or inert gas. 3. Boron phosphate erodes BN in nitrogen at 1400 degrees Celsius; Potassium phosphate reacts at 800 to 900 degrees Celsius. 4, titanium dioxide material has slight erosion at high temperature. 5, react with hot concentrated or molten alkali and hot chlorine gas.
💖Note: The use temperature in the air is 900 degrees, and the surface of boron nitride in contact with oxygen will oxidize beyond 900 degrees. 2 Do not place the crucible in a wet area when not in use. Store tightly. Do not wash with water, the surface dirty directly with sandpaper wipe.
