Translucent Alumina ceramics
Nishimura Advanced Ceramics manufactures Translucent Alumina ceramic which has high total light transmittance and high mechanical strength like single crystal sapphire.
-
High purity Alumina ceramics series
Nishimura handle high purity alumina (99.7~99.99%)
-
Alumina ceramics
Alumina is a fine ceramic with remarkable electrical insulation, corrosion resistance against acids and alkalis, and abrasion resistance. It is applied to various purposes including machine parts and electronic equipment parts.
-
Heat-radiating ceramics
N-9H and N-6H, mainly made from alumina, are categorized in this group.
These materials have a high thermal emissivity, and they are applied to new types of heat sinks utilizing heat radiation. -
N-600 Zero thermal expansion ceramics
Nishimura has developed new ceramic material grade which has almost zero thermal expansion near the room temperature.
Compare with other type of low thermal expansion ceramics, N-600 has outstanding performance below. -
Visible light high reflective ceramic N-9000T
Super pure and ultrafine particle alumina. Reflect electromagnetic wave of visible light region very well. reflectivity is 90 – 94%.
Also it is strong for ultraviolet rays. Always keep color of the ceramic. -
Aluminum Nitride
Well thermal conductivity and electric insulation.
Excellent at thermal shock.ALN-170,200,HYO are available. -
Zirconia ceramics
Zirconia has high electrical insulation, chemical resistance, and remarkable strength at ordinary temperatures in comparison to other ceramics. It is used for abrasion-resistant parts, machine parts, etc.
-
Si3N4 Sillicon nitride ceramics・SiC Carbon nitride ceramics
Si3n4 is the only ceramics material with a greater mechanical strength than Alumina or Carbon nitride, and with a high thermal shock resistance. It is often applied for parts require high mechanical strength in a high temperature area.
-
Anti-Plasma material / Yttria
Yttria has high abrasion resistance against corrosive gases and plasma, and is applied to semiconductor device parts, etc.
-
Forsterite
This product is based on Forsterite. High quality Forsterite does not contain any free Magnesia crystals, and we are one of the corporation which can provide high quality Forsterite.
-
Zircon ceramics
Zircon which is composed of ZrSIO4 is excellent at thermal shock resistance and low thermal expansion.
Zircon is really good for heat-resistant ceramics because it also has hi-level electric insulation at high temperatures.
-
Nishimura Original ceramics (Zirconcordierite)
-Zircon(ZrO2・SiO2)is one of the material which has good thermal shock resistance.
-We mixed this zircon with cordierite. This ceramics advantages are better resistance of thermal shock and stabler firing shrinkage. -
Mullite ceramics
Mullite has high intensity as a alumina ceramic in room temperature. Also it is strong to high temperature condition, and it has small CTE.
-
Color ceramic
Color ceramic
-
Steatite ceramics
Crystals of MgO and SiO2 constitute a steatite.
Main raw material is processed talc, and we add few kinds of auxiliaries.
-
Aluminum Titanate
Aluminum Titanate is composed of Al₂O₃ and TiO₂. These ceramics have the pretty good non-wettability for molten metal.
-
Lithium ceramic N-10J(β-spodumene, petalite)
Li2O-AL2O3-SiO2 kind ceramic. People call β-spodumene or petalite.
-
Cordierite
-This ceramic is MgO・Al2O3・SiO2 kind, and it’s consist on 2MgO・2Al2O3・5SiO2 which is cordierite crystal. This material have two type, called N-23 and N-53.
-Especially, N-53 has much Nishimuras originality. The N-53s special feature is surface which is like after glazed. -
Porcelain (Standerd Porcelain)
This SiO2 and Al2O3 kinds ceramic is the most popular and low cost material.
As a high tension insulator, it is used for suspension-type insulator, pin-type insulator, or bushing. Also it is used for home appliance heater supporter, porcelain bushing, plug, socket, and wiring parts as a low or middle tension insulator. In case of it is used in outside, we will coat its by a glaze. -
Other ceramics
Nishimura Porcelain is providing “low extension rate ceramics” with extreme resistance against heat shock, “high visible light reflectivity ceramics” with high resistance against heat and ultraviolet light, etc.
