Bubble Alumina

Bubble alumina is a new type of high-temperature insulation material, consisting of a-Al2O3 microcrystals.

Size: 5-4mm,4-3mm,3-2mm,2-1mm,1-0.5mm,3-0.2mm,0.5-0.2mm

g/cm3: 0.45,0.55,0.65,0.75,0.85,0.85,0.95

Boron Carbide

Boron carbide is produced through high-temperature smelting of boracic acid and carbonaceous materials in electric furnaces. It boasts a theoretical density of 2.52g/cm3, a melting point of 2450°C, and a micro hardness of 4950kgf/mm2. Its exceptional hardness, second only to diamond and cubic boron nitride, coupled with its high temperature resistance, acid-alkali corrosion resistance, high strength, chemical stability, and lightweight, make it an ideal material across various industries.

Glass Beads

Glass beads, produced from crushed glass and flat glass materials, are processed into spherical shapes through high-temperature melting.

Specific Gravity: 2.3-2.5g/cm3

Refractive index: 1.5-1.7

Material composition: soda-lime glass

SiO2 content: >65%

Roundness: >80%

Ceramic Foundry Sand

Ceramic foundry sand is made from high-quality alumina and vanadium clay, processed through electric fusion, granulation, and screening processes to produce spherical refractory particles.

Spherical grain shape with excellent flow ability and easy compaction. Smooth surface, dense structure, low surface area, requiring less binder and curing agent. It has high compactness, preventing metal liquid infiltration and mechanical sand penetration.

Tabular Alumina

Tabular alumina is a pure sintered alumina, thoroughly calcined without the addition of any additives such as MgO or B2O3. It boasts a coarse, well-developed α-Al2O3 crystal structure, with an Al2O3 content exceeding 99%.

Tabular alumina finds diverse applications, serving as a primary component in refractory materials like alumina-carbon, alumina-magnesia-carbon, magnesia-alumina-carbon, magnesia-spinel, and alumina-chrome refractory bricks.

Chromite Foundry Sand

Chromite foundry sand, with its main chemical component Cr2O3, boasts thermal stability, high thermal conductivity, and excellent resistance to alkali slag. It prevents metal penetration and sand sticking, making it ideal for various stainless steel, alloy steel, and carbon steel core-making applications.

Green Silicon Carbide

Green silicon carbide is made from petroleum coke and high-quality silica, with salt added as an additive, and refined in a high-temperature resistance furnace. It appears as green crystals, is brittle and sharp, and has certain thermal and electrical conductivity.

Grit: 4#5#6#8#10#12#14#16#20#22#24#30#36#40#46#54#60# 70#80#90#100#120#150#180#220#

White Fused Alumina

White fused alumina is produced from high-quality aluminum oxide powder, refined and crystallized through electric arc smelting. It features high purity, excellent self-sharpening properties, resistance to acid and alkali corrosion, high-temperature stability, and stable thermal performance. It is slightly harder than brown fused alumina but less tough. With strong grinding capabilities, low heat generation, and high efficiency, it is suitable for making abrasive tools used for grinding high-carbon steel, high-speed steel, and stainless steel.
