Black silicon carbide carborundum is a wear-resistant material with high hardness. Black silicon carbide is an artificially synthesized material obtained by smelting natural silica and petroleum coke with additives such as salt in a large resistance furnace at 2300 ° C. His Vickers hardness is 2800-3200HV, and his micro hardness is 28-33GPa, indicating strong wear resistance. Black silicon carbide also has good high-temperature stability, low-temperature stability, weather resistance, aging resistance, corrosion resistance, small expansion coefficient, deformation resistance and insulation. Adding materials such as PU, plastic, and resin can increase the material's wear resistance, slip resistance, crack resistance, and oxidation resistance.

防滑臺階條用黑色金剛砂16#24#成分SiC的特性：

1. 高溫化學(xué)穩(wěn)定性和耐腐蝕性能強：碳化硅在1000°以下溫度環(huán)境中性能十分穩(wěn)定，1000°以上穩(wěn)定下碳化硅的表面形成一層二氧化硅薄膜，仍然可保持碳化硅理化性能穩(wěn)定。溫度達到1627°以上，碳化硅的抗氧化能力才會下降。

2. 導(dǎo)熱性能優(yōu)越：常溫下碳化硅的導(dǎo)熱系數(shù)為60-200 W/(M·K)。純碳化硅的理論導(dǎo)熱系數(shù)（熱導(dǎo)率）為490 W/(M·K)，比大部分鋼鐵、銅和鋁的導(dǎo)熱系數(shù)還高。制成的碳化硅陶瓷件的導(dǎo)熱系數(shù)為120-170 W/(M·K)。具有良好的熱傳導(dǎo)性能。

3. 碳化硅具有較低的熱膨脹系數(shù)和抗熱震性能：較低的熱膨脹系數(shù)：25-1400攝氏度溫度下，碳化硅的平均熱膨脹系數(shù)為4.4x10^-6/℃，低于氧化鋁質(zhì)的耐火材料。

4. 高硬度、韌性和高耐磨性：黑色碳化硅莫氏硬度為9.2-9.3，綠色碳化硅莫氏硬度為9.4-9.5，維氏硬度為3100-3400kg/mm2。碳化硅的硬度還會隨著溫度的增加有所降低，在1200度高溫狀態(tài)下，碳化硅的硬度能達到剛玉的2倍。

5. 高韌性：碳化硅磨料的韌性是指在外力作用下破碎的難易程度，以46目為例，靜壓法測試的韌性大概為68-78%。碳化硅的機械強度高于剛玉，以120目粒度為例，碳化硅的抗壓強度為186KN/cm2，剛玉磨料的抗壓強度為100KN/cm2。

6. 粒度均勻：顆粒大小范圍窄，具有良好的流動性和分散性。

7. 清潔度高，游離碳含量低，雜質(zhì)少。

Black silicon carbide features：

1. Strong high-temperature chemical stability and corrosion resistance: Silicon carbide has very stable performance in temperature environments below 1000 ° C. When stable above 1000 ° C, a layer of silicon dioxide film forms on the surface of silicon carbide, which can still maintain stable physical and chemical properties of silicon carbide. The oxidation resistance of silicon carbide will only decrease when the temperature reaches above 1627 ° C.
2. Superior thermal conductivity: The thermal conductivity of silicon carbide at room temperature is 60-200 W/(M · K). The theoretical thermal conductivity (thermal conductivity) of pure silicon carbide is 490 W/(M · K), which is higher than the thermal conductivity of most steel, copper, and aluminum. The thermal conductivity of the silicon carbide ceramic parts made is 120-170 W/(M · K). Has good thermal conductivity.
3. Silicon carbide has a lower coefficient of thermal expansion and thermal shock resistance: at a temperature of 25-1400 degrees Celsius, the average coefficient of thermal expansion of silicon carbide is 4.4x10-6/℃, which is lower than that of refractory materials made of aluminum oxide.
4. High hardness, toughness, and wear resistance: The Mohs hardness of black silicon carbide is 9.2-9.3, the Mohs hardness of green silicon carbide is 9.4-9.5, and the Vickers hardness is 3100-3400kg/mm2. The hardness of silicon carbide will also decrease with the increase of temperature. At a high temperature of 1200 degrees, the hardness of silicon carbide can reach twice that of corundum.
5. High toughness: The toughness of silicon carbide abrasives refers to the difficulty of crushing under external forces. Taking 46 mesh as an example, the toughness tested by static pressure method is approximately 68-78%. The mechanical strength of silicon carbide is higher than that of corundum. Taking 120 mesh particle size as an example, the compressive strength of silicon carbide is 186KN/cm2, and the compressive strength of corundum abrasive is 100KN/cm2.
6. Uniform particle size: The particle size range is narrow, with good fluidity and dispersibility.
7. High cleanliness, low free carbon content, and low impurities.
