PCBN is multicrystalline structure of CBN which been produced by high pressure high temperature(HPHT) sintering of cubic boron nitride(CBN) with binder. It is with high hardness, good thermal stability, thermal conductivity and impact toughness. CBN can be resistant to temperature of 1400 to 1800 .
Boron Nitride(CAS:10043-11-5)
During producing hot bending glass, the glass is slid over the tin. Graphite is used to slide the tin to avoid getting on the glass. We use hexagonal boron nitride(hBN) material instead of graphite. The advantage of hBN is antioxidant and can last long life. hBN can also be used without nitrogen,which is saving costs. We can use H boron nitride material to make various forming molds subjected to your requirement.

CAS 7440-42-8 25kgs/bag,20tons/20'container CAS 7440-42-8 is a black or dark brown powder. When it is oxidized in the air, it will prevent the internal boron from continuing to oxidize due to the formation of a boron trioxide film. It can react at normal temperature Amorphous Boron Powder is insoluble in water, powdered boron is soluble in boiling and most molten metals such as copper, iron, manganese, aluminum, and calcium. 1. Boron fiber has high strength (breaking strength at room temperature is 2744 ~ 3430MPa) and high modulus of elasticity (39200 ~ 411600MPa), which is an excellent reinforcing material. 2. Composite materials made of boron fiber with metal (aluminum, magnesium, titanium, etc.), various resins (epoxy resin, polyamide, etc.) and ceramics are excellent high-temperature structure materials. 3. Reinforcement ceramics made of titanium boride have excellent abrasive resistance and high toughness (up to 10 MPa�·m 1/2 or more), which are used to manufacture conductive parts for heating equipment and ignition devices. 4. Used as a deaerator in the metallurgical industry and an additive to improve the structure of metal grains. 5. Boron-cast iron is widely used in automobile, tractor, machine tool and other manufacturing industries.
Calcium Nitrate with Boron is a highly efficient source of Calcium and Nitrogen for plants. It enhances yield quality and prolongs shelf life of the produce without any traces of sulphate. It's a fortified fertiliser which includes boron between 0.2 to 0.3%.

Quick supplement nitrogen, supplying calcium and boron directly. Boron is the main element of promoting flower and fruit swelling. It is also efficient in disease resistant, crack resistant and crops quality improvement, which is widely used for greenhouse and large areas of agricultural land. It is a free-flowing material. Its hygroscopic nature means that it readily dissolves when in contact with the soil in humid conditions or a night dew. This formulation offers low risk of scorch and is often used as a final topdressing to a wide range of high value crops that have a requirement for extra boron. Packing: 25kg bags, 50kg bags, 1200kg jumbo bags, and customer's marking bags. Handling and Storage: Store in a cool and dry place, away from moisture, heat.

Sp.gr.2.95¡ª3.01g/cm3, melting point about 1000 centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. It¡¯s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively. The size distribution can be sandy (80mesh), powder (200mesh, 325mesh), granular (0-10mm). Other items can be specified according to special requirement. Specification: Molecular FormulaNa3AlF6 Molecular Weight 209.94 Properties It is a colorless monoclinic crystal, but often appears off-white, pompadour, straw yellow or black due to impurities. It has relative density of 2.9-3.0, mp 1000. It is slightly soluble in water, and its aqueous is acidic. It decomposes to release poisonous HF gas while meeting sulfuric acid. UsagesIts mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for resin and rubber-boned abrasive wheels.
